Best casting would go to Butch Cassidy and the Sundance Kid.
But as that is only really two (albeit perfect) main characters and you wanted a wealth of superstars I would go for the Great Escape as the best assembled cast.
Longest Day gets my vote – useless fact Richard Todd met himself in the film (he played Major Howard in the film and was the battalion commander who made contact with Major Howard in 1944 – there is a scene of this in the film)
Great to see a few votes for 12 Angry Men, I was thinking it was one of those old films that’s slipping out of the collective consciousness – no one I know has seen it.
Musician-wise, hard to argue with Blues Brothers really. Bit sad though these days, seems like every time I watch it there’s more that aren’t with us anymore (Duck Dunn passed quite recently I think).
Great Escape
Towering Inferno
Poseidon Adventure…original
the godfather 1&2
Heat
Magnificent Seven
The Vikings
Some like it Hot
Angels with dirty faces
Treasure of the Sierra Madre
Richard Lesters Three Musketeers
Prisoner of Zenda 1937
Not sure I’ld agree with all of them being poor films.

Are we talking about the best cast, as in the best ensemble of actors, or the best cast as in the best casting of actors to roles!? Apologies if this has already been answered….
Highlander (A Frenchman pretending to be Scottish, a Scotsman trying to be Egyptian and an American trying to be a Russian – and it all works brilliantly!)
How about Humphrey Bogart, Burt Lancaster, Ava Gardner, Bette Davis, Cary Grant, Ingrid Bergman, Lana Turner, Kirk Douglas, James Cagney, Joan Crawford, Vincent Price, Barbara Stanwyk… plus Steve Martin & Rachel Ward
Actually, in terms of casting actors to roles I can’t think of many who would’ve done a better job than Viggo Mortensen, Ed Harris and Naomi Watts in A History of Violence
