- — Marty recognizes the "Man from Space" episode of The Honeymooners
A rerun was a re-airing of a television episode that had previously debuted at an earlier date or time.
On October 25, 1985, Marty McFly was eating dinner with his family as they watched a rerun of an episode of The Honeymooners titled "The Man from Space". When Marty ate dinner with his mother's family on November 5, 1955, the Baines family was watching the same episode, but it was being shown for the first time.
When Marty exclaimed that he had seen "The Man from Space" before, his uncle Milton Baines immediately asked how this could be, as the episode was brand new. Except for a few shows that were recorded on kinescope or film for showing in different time zones the same night, all television shows were performed and broadcast live. Marty sheepishly replied that he saw it when it was a rerun. Milton had never heard of the term, since although The Honeymooners was recorded on film using the Electronicam system at the same time as it was broadcast live, television stations had not yet started showing these recordings.
Behind the scenes
- In several non-English dubs of the movie, such as in Italy, where Back to the Future is called Ritorno al futuro, the word 'rerun' doesn't exist — usually because the country concerned has not yet adopted the policy of re-airing episodes of television shows. Thus, in Ritorno al Futuro, Marty says to Milton that he saw the first-run "Man from Space" episode of The Honeymooners "on video" — i.e. a VHS videocassette.
- Reruns are known as repeats in the United Kingdom.
