 By the time the Beatles stopped touring in late 1966, their promotional films, like their recordings, had become highly sophisticated.In May 1966 they filmed two sets of colour promotional clips for their current single "Rain"/"Paperback Writer" all directed by Michael Lindsay-Hogg, who went on to direct "The Rolling Stones Rock and Roll Circus" and the Beatles' final film, "Let It Be".The colour promotional clips for "Strawberry Fields Forever" and "Penny Lane", made in early 1967 and directed by Peter Goldman, took the promotional film format to a new level.
