I think the most recent thing I saw Richard Griffiths in was the first episode of Episodes, in which he plays a Richard Griffiths-type actor, star of a British show about a school called Lyan's Boys, which is about to be remade for American TV. He auditions for his own role, but is rejected in favour of Matt LeBlanc (ably played by Matt LeBlanc)...
