During the Joseph McCarthy-inspired "Red Scare" era in the 1950s, this was one of the films labeled "subversive" by the HUAC (House Un-American Activities Committee) because it was alleged to have contained dialog that might be construed as pro-communist. Writer John Wexley was even "blacklisted". It wasn't seen again in the United States until the mid-'70s.
The original titles for the project were "No Surrender" and "Never Surrender" They had to choose a new title because a book was published with a similar title during production. Producers held a contest among the cast and crew to choose a new title. A production secretary submitted the winning title and won $100.
