Harriet PriceWhen As Deep as the Grave arrives in cinemas later in 2026, audiences will watch Val Kilmer — who died on 1 April 2025, aged 65 — deliver a performance he never physically shot. Using archival footage, family photographs, and AI voice synthesis, the film's producers reconstructed the actor's likeness with the blessing of his daughter Mercedes and son Jack Kilmer. It is the first major Hollywood release to resurrect a deceased star via artificial intelligence, and it is already forcing estate lawyers on both sides of the Atlantic to confront questions that UK inheritance law is not yet equipped to answer.
Val Kilmer's Estate: The Numbers Behind the Headlines
When Kilmer died of pneumonia in Los Angeles, he left behind an estate estimated at between $10 million and $25 million, comprising a California home, a New Mexico ranch, art collections, and — crucially — intellectual property rights tied to four decades of film and music work. His two children are expected to inherit the bulk of those assets, according to finance-monthly.com.
In the United States, his estate may have triggered the federal estate tax at 40 per cent on any value exceeding the 2025 individual exemption threshold of $13.99 million, potentially costing the Kilmer estate several million dollars in tax liability. California, where he died, has no state-level estate tax — but the federal exposure alone has prompted American estate attorneys to deploy Kilmer's situation as a live teaching case on the cost of inadequate tax planning.
The more novel question — and the one now attracting close attention from legal professionals in Britain — concerns his digital assets: the AI-synthesised voice, the image rights, and the royalties flowing from the posthumous performance in As Deep as the Grave. Who owns a dead person's digital self? What happens when there is no specific provision in a will? And what liability falls on a family that simply did not know to ask?
Why UK Estate Lawyers Are Watching This Case
UK inheritance law has struggled to keep pace with digital assets. The Law Commission has been consulting on reforms to address precisely this gap — acknowledging that wills drafted even five years ago almost certainly fail to anticipate voice clones, AI likenesses, or social media accounts with meaningful commercial value.
The Kilmer situation crystallises the risk. His estate could participate in As Deep as the Grave because his children gave their blessing informally, and because the production company was cooperative. But in a contested estate — where beneficiaries disagree, where a business partner claims rights over shared recordings, or where an ex-spouse argues that digital assets formed part of matrimonial property — the outcome would be entirely unpredictable under current UK law.
Estate solicitors in England and Wales are increasingly advising clients to treat digital identity as a distinct asset category, as significant as property or pension. As seen in the ongoing dispute over Prince's $156 million estate, celebrity cases consistently expose the brittleness of generic wills when intellectual property is involved.
The stakes extend well beyond Hollywood. In 2026, millions of UK residents maintain YouTube channels, podcasts, Substack newsletters, or businesses built on their personal brand — including a recognisable voice or face. Without a will that specifically addresses those assets, HMRC and the courts treat them as residual estate, distributed according to default rules written long before AI existed.
Expert Take: Three Inheritance Lessons from the Kilmer Case
Estate law specialists point to three direct lessons from the Kilmer estate for UK residents.
Update your will for the digital age. A standard will drafted before 2020 almost certainly contains no provision for voice recordings, AI training data, image rights, or platform accounts. If those assets have commercial value — even modest commercial value — they require explicit beneficiary designations and, ideally, instructions on permitted uses.
Think about tax planning before it becomes urgent. Under UK inheritance tax rules, estates above the nil-rate band of £325,000 are subject to a 40 per cent charge on the excess. Married couples who legally optimise their estate structure may benefit from a combined threshold of up to £1 million — but only if the correct paperwork and trusts are in place before death. Waiting until illness strikes is almost always too late to implement meaningful mitigation.
Digital assets need a named custodian. The Kilmer family could engage with the film's producers because they had informal control of his archive. Most families would not be in that position. A letter of wishes — separate from the will but held alongside it — can name a trusted person to manage, monetise, or shut down digital accounts, and can provide explicit instructions on whether AI use of the deceased's likeness is ever permitted. According to analysis of UK celebrity estate lessons, the absence of such guidance is the most common cause of family disputes in digital estate cases.
The Voice That Keeps Earning: What This Means for Ordinary UK Earners
Val Kilmer is a film star. His case reads as exceptional. But the underlying dynamic is not.
Consider the growing number of UK residents who earn money from their voice, face, or personal brand in ways that would have been inconceivable in 2010: freelance voiceover artists who licence samples, podcasters with tens of thousands of subscribers, small business owners whose face appears in years of commercial content, educators who have recorded hours of online courses. For each of them, a death without a digital estate plan does not just create legal complexity — it destroys value that no amount of retrospective legal action can fully recover.
The As Deep as the Grave case demonstrates that even a damaged voice — Kilmer's was severely affected by his tracheal procedure for throat cancer — retains commercial value when combined with AI reconstruction. The question for UK families is not whether their assets are valuable enough to plan around. It is whether they are leaving their loved ones the legal tools to protect that value.
Concrete Case: A Freelance Voice Actor in Birmingham
Consider a 52-year-old freelance voice actor based in Birmingham — call him David — who has spent a decade building a portfolio of commercial narrations, four audiobooks, a podcast with 38,000 monthly listeners, and a library of 600 licensed voice samples. He earns £35,000 per year from these assets, making them a substantial part of his financial life.
David dies unexpectedly from a cardiac event, having last updated his will in 2016 — before any of his digital assets existed.
Under current UK inheritance tax rules and intestacy practice:
- His estate is valued at £435,000 (home equity of £320,000 + digital assets conservatively valued at £115,000)
- The nil-rate band is £325,000; the taxable excess is £110,000
- Inheritance tax due: £44,000 (40 per cent of £110,000), payable within six months of death
But the more damaging problem is not the tax charge — it is control. Because the 2016 will makes no provision for the podcast, the recording library, or the licensing agreements, David's executor (his brother, a secondary school teacher with no background in IP law) must decide without guidance whether to licence the recordings, whether to allow a production company to use David's voice for AI synthesis, or whether to simply let the accounts lapse due to inactivity. There is no instruction. The podcast platform removes the account after 90 days of non-activity. The voice sample library, unlicensed and unmanaged, generates no further income. The digital asset worth £115,000 effectively disappears.
If instead David had spent three hours with an estate solicitor in 2025 to update his will:
- He could have named a digital executor with specific authority over IP assets and licensing decisions
- He could have granted or withheld explicit permission for future AI use of his voice — a single clause that would have cost nothing to add
- By structuring the digital assets within a simple trust, he might have deferred IHT liability on that portion of the estate
The three-hour appointment would have cost approximately £350. Failure to act cost his family £44,000 in tax and the complete loss of an asset worth £115,000 in annual income. That is a total exposure of over £150,000 for the price of an afternoon.
What UK Families Should Do in 2026
Audit your digital footprint. List every platform, account, or asset that generates income or has commercial value — including things you consider side projects. A podcast with a modest audience, a stock-photography portfolio, or a self-published book on Kindle all count as estate assets.
Consult a solicitor who understands digital assets. Ask specifically whether they have experience drafting wills that include voice recordings, image rights, AI licencing clauses, and social media accounts. The Law Commission's ongoing digital assets reform consultation signals that the legal landscape will shift — a solicitor who is actively following that process is a valuable guide.
Use a letter of wishes alongside your will. Unlike the formal will, this document can be updated at any time and gives your executor practical instructions that a legal document cannot easily accommodate — including, for example, exactly the question that Val Kilmer's family faced: would you want an AI company to use your voice after your death?
For estates approaching the £325,000 nil-rate band threshold, proactive planning with both a solicitor and a financial adviser is strongly advisable. Gov.UK's guidance on inheritance tax sets out the rules and exemptions in full, and an expert consultation can identify which structures apply to your specific circumstances before it is too late to act.
Val Kilmer's children gave that permission, and a Hollywood film is the result. Millions of UK families with far smaller estates face the same question eventually. Without professional legal and financial guidance, they will face it without any framework at all.
