not counting laurel & hardy,since all their films were american....so...my picks for the greatest british film comedians are....peter sellers.....terry thomas.....bernard cribbens
Rowan Atkinson
John Cleese
I know his humor is low-brow and immature, but I laugh like a little kid when I watch him.
simon pegg.
I had considered him as well.What about Alec Guinness? He's wonderful in his Ealing films.
+1 IMO Fawlty Towers stands alone at the pinnacle of TV comedy.
