Almost didn't offer the wise crack because she, the actress, is a commie pinko traitor in real life.
Lee Marvin, Nat King Cole and Stubby Kaye stole the whole show anyway!
I always admired Lee Marvin a real life WW2 Pacific War Marine Veteran, who was quoted that he hated acting in The Dirty Dozen as it was nothing like real Combat but he needed the money, as for Hanoi Jane Fonda no respect for her at all
