There are no female speaking parts in this movie.

Several years before Universal put this movie together, it had a bigger-budget version planned with Tony Curtis and Dean Martin as the Geste brothers and Charlton Heston as Sgt.Markov. That version was not made.

When Universal intended making a large-scale production, it had planned to use an all-star British cast--Richard Burton, Peter O'Toole and Albert Finney. It was eventually deemed to be too expensive so instead was filmed on the Universal back lot.

Gene Kelly was originally signed to direct.
