I'm not usually a fan of biographical movies where someone plays someone we know well. I always sit there and (a) notice all the ways in which the actor playing the well-known personality doesn't act, look or sound like him. And then there's (b) in which I sit there noting all the ways in which the well-known individual's life has been changed for dramatic reasons when the real story would have been more interesting. But I kinda enjoyed the 2002 TV-movie Gleason, all about Jackie Gleason.
It was co-produced and written by two good stand-up comics, Rick Podell and my pal Mike Preminger…but I didn't know Mike that well when I found myself enjoying it in 2002. And it starred, of all people, Brad Garrett as Gleason. Good makeup made him look portly enough to play the part while clever camera angles made him look short enough. (Garrett is 6'8" whereas Jackie was 5'10".)
Anyway, the whole thing's online (legitimately) and free to watch. You might enjoy it too…
