The fake documentary comedy was created by Gervais and frequent collaborator Stephen Merchant and stars veteran actor Warwick Davis as a version of himself.
The 'Star Wars' and 'Willow' actor will star as "a down-and-out little person desperately trying to hustle and connive his way back into the spotlight," according to HBO.
Each episode will feature cameos from famous folks including Johnny Depp and Steve Carrell. Gervais and Merchant will have minor roles on the series.
'Life's Too Short' debuts on BBC Two later in 2011. The HBO launch will be in 2012. The first season will be six episodes.
