Harvey owned the rights to the book on which John Osborne's early script for the film "The Charge of the Light Brigade" (1968) was partially based, Cecil Woodham-Smith's book "The Reason Why" (1953). He intended to make his own version. A lawsuit was filed against director Tony Richardson's company Woodfall Film Productions on behalf of the book's author. There was a monetary settlement, and Harvey insisted on being cast in a cameo role (being cast as Prince Radziwill) as part of the agreement for which he was paid £60,000. Charles Wood was brought in to re-write the script. Harvey's scenes were cut from the movie at Richardson's insistence except for a brief glimpse as an anonymous member of a theatre audience which, technically, still met the requirements of the legal settlement. John Osborne asserted in his autobiography that Richardson shot the scenes with Harvey "French", which is film jargon for a director "going-through-the-motions" because of some obligation, but with no film in the camera.
