The Mag 7 had a fair roll call but some got more famous for being in the movie than the other way round so it's a toss up. e.g. Horst Bucholtz, Eli Wallach. All had impressive careers though, except Brad Dexter. (who?)
sheesh... the names in the cast sure bring back memories... imagine.... Arnold Stang... Jimmy Durante, Zasu Pitts, Joe E. Brown, Buster Keaton , Ben Blue, Jerry Lewis... My whole:love_heart: life just passed before my eyes...
You're twisted enough to count that a classic too eh?
... Are we comparing apples and oranges with these movies? Most famous in genuine plot character roles, or just as cameos?
Mad Mad... had everybody in it but most were really just 'extras' in the scheme of things.
I'm still thinking Mag 7, as of the 8 major roles 7 were filled by 'famous' actors. That's a pretty good ratio.
Brynner, McQueen, Coburn, Bronson, Vaughan, Bucholtz and the sole survivor, Wallach, and not a ham among them!
