The film was shot at Goldwyn Studios starting in November 1964. Al Zimbalist said he didn't want to glamourise the gangsters. "We just wanted to tell the story how three young men went wrong in hopes no other young people would make the same mistakes they made," he said.
Shot cheaply in 17 days without period costumes, Robert Conrad recalled that he only did the film to repay a favor to his friend Nick Adams.
Ashley added that the movie "may have been the most fun of everything I ever did. At the time all three of us [Adams, Conrad and himself] were divorced. We were all living up in Nick's house. This film came along through Allied Artists. They actually approached Nick, and Nick said 'You should go see about getting John and Bobby'. We all agreed to it and we basically rewrote it. We took a lot of liberties with these three guys, but it was a lot of fun and a real pleasant experience."
During filming, the management of Allied Artists were engaged in a proxy fight with rebellious shareholders.
Adams and Zimbalist wanted to make another movie together, Guns of the G Men. However it was never made.
The Los Angeles Times called it "a B picture with A virtues... good performances... crisp direction... fast moving and full of action.
