“Everybody on the Paramount lot had a crush on her,” says producer A. C. Lyles, then an office boy. And once the public was treated to the titillating sight of an unclothed Colbert frolicking in a bath of ass’s milk, she attracted legions of new admirers. “Two men with cardboard stirred up the milk at the other end of the bathtub so it would make waves,” she disclosed to Rex Reed, “and the milk went below my nipples. DeMille would yell ‘Cut!’ till they got more milk above the censorship level. I was sweating like hell in all that hot milk!” DeMille, however, was forced to use the footage already shot when, after a dinner break, everyone returned to the set to find that the milk had cooled down and curdled into cheese.
