During filming of
Faster, Pussycat! Kill! Kill! (1965) was so afraid of having his caps damaged during his fight scene with Varla (the incomparable
Tura Satana), she (who actually choreographed the fight) did it in 'slow motion' (she said she actually had to 'pull and lift him' during it to make it appear they were tussling), so as to not possibly injure him.
