- "Crazy drunk driver..."
Red is a street bum that resided in downtown Hill Valley in 1985, and was known to spend the night listening to the radio while lying on a bus stop bench with an advertisement for California raisins on it.
On October 26, 1985, after Marty McFly drove back to his present day in the DeLorean time machine and crashed into the Assembly of Christ, Red woke up, saw this and commented on him being a "crazy drunk driver". Marty apparently knew him, as he addressed him by name when he saw him.
In 1973, Biff used the fact that Red was a bum to his advantage. He had one of the members of the Hill Valley Police Department, which he owned in this ABC timeline, plant George McFly's wallet on Red. This made it look like Red had killed George in the alley, rather than Biff.
By 1985, Red was again on a bench as a street bum. In this alternate reality, Marty bumped into him outside a nightclub (named Sin) and Red, not recognizing him, yelled; "Watch where you're goin', you crazy drunk pedestrian!!".
Behind the scenes
- It is disputed whether this is former mayor Red Thomas, but has been generally accepted that he is not. According to Bob Gale's commentary on the Back to the Future DVD set, the name of the bum was ad-libbed by Michael J. Fox. Gale also commented that the photo of the mayor in 1955 on the side of the campaign van was that of set decorator Hal Gausman, whereas the bum was played by George Flower.
