Title: F/X
Content:  The unsolicited screenplay was written by two novice writers, actor Gregory Fleeman and documentarian Robert T. Megginson. Producer Jack Wiener read their script, which was submitted as a low-budget television movie, and felt that it should be made into a theatrical release. Wiener and his co-producer Dodi Fayed hired Robert Mandel, an Off-Broadway director. They did not want to hire an action director, but instead wanted a director who would bring a realistic touch to the film and make the audience care about the main character. Mandel accepted the job because he wanted to dispel the perception that he was a "soft, arty director".

Title: Flashman (novel)
Content:  " Lester later said, "it came in that very bad year for United Artists when they wrote off 90 million and cancelled nearly everything." After the failure of The Bed Sitting Room Lester did not make a film for five years. In August 1971 Stanley Baker was attached as producer with Lester still to direct. However, the film was not made.

Lester said it "came about at the time when the film industry began to collapse within itself. A sort of implosion. It’s a very expensive project, a period film where at one point 13,000 of the British Army have to retreat in January from Kabul into India, being attacked by hordes of Afghans. It’s not the sort of thing that you can do on a shoestring... To do it properly it would be a very expensive film; and I don’t think one should do it
