Val Kilmer is to reunite with Warwick Davis for 'Life's Too Short'.

The 53-year-old actor will appear alongside the 'Harry Potter' star for the first time since they were in 1988 fantasy film 'Willow' together in a new one-off special of the sitcom mockumentary about the diminutive star's life in the showbiz spotlight.

Stephen Merchant - who writes and directs the series with Ricky Gervais - said: "I think fans of 'Willow' are going be really surprised to see Warwick Davis and Val Kilmer reunited onscreen. Almost as surprised as Val will be when he finds out what we're paying him."

Former 'Family Fortunes' host Les Dennis, TV presenter Keith Chegwin and ex-'EastEnders' star Shaun Williamson will also reprise their roles as themselves in the episode of the show, and Ricky and Stephen have short parts in the 60-minute special.

Ricky added: "I can't wait to work on the 'Life's Too Short' special with the likes of Keith Chegwin. It will make a nice change from working on 'The Muppet Movie' opposite weird little things with squeaky voices."

Warwick played the titular character in Ron Howard-directed film 'Willow' - which sees his alter-ego, a reluctant dwarf, protect a special baby from an evil queen - and he is delighted to be teaming up with Val again.

He explained: "I am thrilled to be able to step back into Warwick's shoes again for this special. Ricky and Stephen's scripts are always a gift to play and the inclusion of Val Kilmer is nothing short of genius."
