Actually, they had a falling out when June Mathis' script for "The Hooded Falcon" that had been written in a hurry as she was working at another film company, was rejected and Valentino and his wife Rambova hired a script doctor without informing Mathis. When informed, she cut off her relationship with both of them. They only reconciled at the premiere of later at the July 1926 premier of "The Son of the Sheik" in Los Angeles which she attended. By that time Rambova was out of the picture.
