He was under contract to M-G-M, first as a choreographer and then as a director, for over 20 years and all the films he directed were made for that company except his last one, "Walk Don't Run" (1966), which he made for Columbia. In the later days of his Metro contract, he was often called in to direct additional scenes for other people's movies - these tended to be very unlike his own films, and included the erotic drama "Go Naked In The World", the western epic "Cimarron" and the Biblical epic "King Of Kings". All these assignments were uncredited.
