Sorry but Brando was a joke in Guys & Dolls.Why the ability to sing was considered unimportant in casting a musical must remain a Hollywood mystery. Sorry again GF fans but Brando was terrible in the GF slurring his speech like a stroke victim. He couldn't even remember his lines.The director had to post them all over the room like highway billbords. I am not saying Sinatra should have gotten the role but there were plenty of other possibilities,not the least of which was Danny Thomas. The film would have been a great comeback vehicle for him.The film did nothing to revive Brando's career.He was better in the Freshman.
