The colour promotional clips for "Strawberry Fields Forever" and "Penny Lane", made in early 1967 and directed by Peter Goldman,[14] took the promotional film format to a new level. They used techniques borrowed from underground and avant-garde film, including reversed film and slow motion, dramatic lighting, unusual camera angles, and color filtering added in post-production. At the end of 1967 the group released their third film, the one hour, made-for-television project Magical Mystery Tour; it was written and directed by the group and first broadcast on the BBC on Boxing Day 1967.
