Val Kilmer

Sadly, it looks as though there will be no second series of Life's Too Short, but my favourite comedy of 2011 enjoyed a last hurrah, thanks to a one-hour special that addressed many of the faults, and played to the strengths, of its first run.

Gone were the gratuitous physical humiliations visited upon star Warwick Davis, along with the David Brent mannerisms bequeathed him by writers Ricky Gervais and Stephen Merchant.

Instead, Davis was given free rein to explore the comic potential of his complex, conflicted and constantly embattled character. Rosamund Hanson provided scene-stealing support as dippy secretary Cheryl.

Extra helpings of guest stars playing either unflattering or unsympathetic versions of themselves were also served up. Shaun Williamson, Keith Chegwin and Les Dennis all made a welcome return - "Three Z-list celebrities make one D-list celebrity," encouraged Davis as they embarked on their All Star roadshow - with a surprise appearance from the former Hollywood star and one-time screen Batman Val Kilmer.

With an enthusiasm that bordered upon self-flagellation, Kilmer portrayed himself as a slightly deranged fantasist and maniacal con man who raises, and then shatters, Warwick's dreams of a sequel to Willow.

Painfully poignant, beautifully played and constantly inventive, this one-hour special conclusively proved that Life's Too Short's own end was also premature.

It may not be fashionable to approve of anything with Ricky Gervais's name on it. But this Life's Too Short Special (BBC2, Saturday) - with Val Kilmer, along with Les Dennis, Keith Chegwin, and Shaun Williamson joining Warwick Davis - is a piece of genius. There's nothing Gervais hasn't done before. An obsession with disability: check. Fading slebs making tits of themselves to highlight the horrors of the fame game: check. More squirminess than a sack of snakes with the squits: check. But it's done with such a breathtaking boldness that it's impossible not to gasp with a mixture of shock'n'awe. I mean he gets Chegwin to revisit not just his drunkenness but his nakedness too!

Actually the funniest moment is when Les, Keith and Shaun are sharing a hotel bed, to save money. "Not while I'm reading [Sartre as it happens]," says Shaun, when Cheggers reaches down to say hello to little Cheggers, if you know what I'm saying.

Then Gervais chucks in the curveball of touchingness (the other sort). It shouldn't be surprising - he usually does - but it somehow catches you off-guard. Especially poignant if you've just watched Kavana on The Voice.

Things look promising for Warwick Davis in this hour-long Easter special when Val Kilmer, his co-star in 1980s fantasy Willow, turns up in London to tout a possible sequel. But the main action involves our diminutive hero's attempt to resurrect the careers of Les Dennis, Keith Chegwin and Shaun Williamson ("Barry from EastEnders") via a low-rent pub roadshow. It's a cruel extended riff on the backwoods of fame and occasionally the horrible edginess of it is very funny.

"I used to be a lying, conniving, selfish little shit." Yes you did, Warwick Davis. But for the purposes of this one-off valedictory special, that won't do. Because if no one cared, that would prevent Ricky Gervais and Stephen Merchant from tacking on another of their increasingly trite redemptive endings. But is anyone really that bothered about Life's Too Short anyway? Surely not like they were about Extras - and certainly not like they were about The Office.

As we rejoin Warwick, he's 'a changed man'. He's kind, conscientious and generally rather likeable. So when this concluding cavalcade of horrors - which includes a mendacious Val Kilmer, the further self-abasements of Les Dennis and Keith Chegwin and yet more smug, sideline rubbernecking from the show's creators - dumps Warwick in the mire, we're supposed to feel his pain. Sadly, this particular group hug hasn't been earned, so the conclusion feels as hollow and joyless as the rest of the series.

There's awkwardness abound and a stark-naked Keith Chegwin as Warwick attempts to scrape together enough money for a sequel to Willow, while balancing a touring cabaret show he's running that stars Cheggers, Les Dennis and Shaun Williamson. Oh and Val Kilmer's in there somewhere too. Maybe he'll join the trio for an encore of The Boys Are Back in Town...

Val Kilmer to guest star in final Life's Too Short

Hollywood actor Val Kilmer will appear in a one-off special of TV comedy Life's Too Short nearly 25 years after he and Warwick Davis last worked together.
