Out of that list I would have to say Jack Lemmon, although Gene Wilder has me in stitches. My own personal choice however - purely for comic acting- is the great Harold Lloyd. I think that the most underrated comic actor of all time though, is Bob Newhart.
Doh, I voted for Peter Sellers, I guess you lot are too young to remember him in Pink Panther!! Not that the others aren't brilliant too, it was a hard choice, Gene Wilder would definitely be my 2nd!
Other choices I can think of immediately would be: Ben Stiller Norman Wisdom Chevy Chase Richard Pryor Eddie Murphy
Not all the GREATEST, I know, but its hard to narrow it down to one, when times have changed so much, god,I sound well old eh!!
I chose Peter Sellars, loved him in Stranglove and Pink Panther and no, Im not really like old, but my favourite comedy actor is Steve Martin closely followed my Michael Palin.
I voted for Jack Lemmon because his performance in Some Like It Hot blew me away
But Peter Sellers as the Pink Panther comes a close second
