According to
Albert S. Ruddy and
Burt Reynolds on the DVD Commentary, for reasons unknown,
Robert Aldrich didn't like actor
Michael Conrad (Nate Scarborough) and would always insult him by calling him the "Polish Princess". Finally, when they were filming the scene between Paul Crewe (Reynolds) and Scarborough (Conrad) where Nate says, "There's only two things you've got left: Your pride and your balls . . . " Aldrich liked the scene so much that he rewarded Conrad with a candy bar, which was the daily award Aldrich would give out to whomever did the best work that day. Conrad, who had endured Aldrich's insults throughout filming, was actually moved to tears. Aldrich stopped referring to Conrad as the "Polish Princess" for the rest of the shoot.
