 Although Fox insisted on maintaining CinemaScope for a time, some actors disliked the system. For Fox's 1965 production Von Ryan's Express, Frank Sinatra reputedly demanded that Auto Panatar lenses be used. Such pressures led Fox to completely abandon CinemaScope for Auto Panatars that year; Von Ryan's Express was the studio's first picture with Panavision lenses. To meet the extraordinary demand for Panavision projection lenses, Gottschalk had Bausch & Lomb CinemaScope lenses retrofitted into Panavision housings with a new astigmatic attachment, improving them greatly. This was revealed many years after Gottschalk's death; a lead designer from Bausch & Lomb, who had been involved with the original CinemaScope project, came to work as a designer for Panavision and — after opening some of the older lenses — figured out the secret.
