Sloan Wilson wanted Monty Clift as Tom Rath
I read an interview with Sloan Wilson, in which he stated he would have preferred Montgomery Clift as Tom Rath in the film version of his best-selling novel, rather than Gregory Peck.
Although Wilson liked Peck, he thought Clift more accurately represented the character of Tom Rath, in physicality as well as in demeanor, as Wilson had written him. Peck's screen image, Wilson felt, was too large, confident and heroic for his fictional protagonist.
