My only issue with this movie.
4 or 5 of the Dozen had no personalities and were played by anonymous, no-name actors. Trini Lopez was a singer and reasonably well known, but his character didn't have that much to do so I have to include him in this. The characters Vladek, Gilpin, Sawyer and Bravos were almost totally anonymous cannon fodder.
If only they could have gotten guys like Steve McQueen, James Coburn, Clint Eastwood, James Garner and fleshed out the roles. Even second-stringers like Neville Brand would have been better than those no-name guys. The Magnificent Seven (1960) holds the title of best 60s tough guy ensemble.
