Davis previously teamed up with Ricky Gervais and his writing partner Stephen Merchant to pen the mockumentary, about the everyday life of a dwarf, and now the Bbc has ordered another one-off episode of the show.
The upcoming comedy will feature a guest appearance by Kilmer, Davis' co-star in 1988 fantasy film Willow, and the funnyman can't wait to reteam with his old pal.
Davis says, "The inclusion of Val Kilmer is nothing short of genius."
And Merchant jokes, "I think fans of Willow are going be really surprised to see Warwick Davis and Val Kilmer reunited on screen. Almost as surprised as Val will be when he finds out what we're paying him."
The Life's Too Short special is set to air in the spring (13).
