After working with Peter Sellers on "The Waltz Of The Toreadors", Mankowitz joined forces with the actor in an independent film company called Sellers-Mankowitz Productions, and they announced, as their first production, a comedy film to be entitled "Memoirs Of A Cross-Eyed Man". But the unpredictable Sellers went cold on the idea and found he had little fondness for the duties and responsibilities of a film producer, so he wound up the company very soon after it had been launched, without its having made any films. Later, Mankowitz described him as a "treacherous lunatic" - they were never reconciled.
