I know it was made in 1967, but the acting...
...was so bad the actors shouldn't have taken money for it.
Jason Robards was so bad that he should've been embarrassed. He was so wrong for the part that it made me feel embarrassed. He looked TOO unlike Capone facially, physically, and even ethnically - totally unbelievable.
And George Segal played his part in the Alan Ladd style of wooden or cardboard cutout. I've never seen him in a movie where he looked so out-of-place. His bully was so over-the-top that it was cartoonish.
Ralph Meeker played the part of looking like Ralph Meeker perfectly. He was a touch less wooden than George Segal, but only because he was playing himself.
All in all, I found the acting was so bad because most of the characters were completely miscast in the first place. Although I did watch it from start to finish, I kept finding myself wondering who chose this cast of actors? I think it was the most miscast movie I've ever seen. It was supposed to be about mostly Italian/American gangsters and they couldn't even LOOK like them never mind play them.
