"We're not leaving comedy behind, but we'd like to have a go at something more dramatic," Gervais said during a London event promoting the second season of "Extras."
"Extras" centers around struggling actors working on movie sets. Cameo guest shots during the new season will include David Bowie, Orlando Bloom, Robert Lindsay, Ian McKellan and Daniel Radcliffe. The show is co-produced by the BBC and HBO.
Gervais said he is inspired by "innovative" and "audacious" dramas being shown on U.S. TV, The Guardian reported.
He said British TV "can't do" or "don't do" anything close to "24," "The Sopranos," "The Wire" and "The Shield."
