Here are a few examples:
* "The Night of the Hunter" (1955): He starred alongside Lily Miles, who played the role of "Rachel Cooper."
* "Thunder Road" (1958): Mitchum worked with James Edwards, who played a supporting role as "Sheriff Pete."
* "The Sundowners" (1960): While not a starring role, Peter Coe played a small part in this film.
* "The Longest Day" (1962): The film featured Leonid Kinsky and Harold J. Stone in supporting roles.
It's important to remember that in the 1950s and 1960s, opportunities for Black actors were severely limited due to the prevalent racism and segregation in Hollywood. Mitchum's collaborations with these actors were significant, particularly given the historical context.
