According to Kim Hunter: "The tensions on the set contributed to his (Rossen's) death. I don't think I want to talk about it. Since then, Warren has grown so; at that time, he wasn't ready to be a star. He knew it and was scared! In rehearsal, he'd be great. The closer he got to the camera, the more he'd retreat. He'd cut half his lines, which made Warren interesting and the rest of us talky as hell! He gave Jean no help whatsoever. She was damn good in a demanding role. At the wrap party, a group of people threw Warren into a stream".
While filming, Robert Rossen took time out to present the award for annual creative cinema sponsored by the Society of Cinematologists. The three winners were George Houston, Robert Shaye, the future head of New Line Pictures and one Martin Scorsese.
