A payphone was a coin-operated public telephone.
There was a payphone situated in a booth in Lou's Cafe in 1955, which Marty McFly made use of while he was making a call to Emmett Brown, after having looked up his number in the telephone directory. Local calls cost 5¢.
Behind the scenes
- In a deleted scene from Back to the Future, Mark Dixon traps George McFly in a payphone booth at Hill Valley High School during the Enchantment Under the Sea dance, and Mr. Strickland refuses to break him out.
- In real life, by 2015 most outside payphones had been removed because of the prevalence of cell phones, something that Back to the Future Part II obviously didn't foresee (although bulky cellular telephones were in use in 1989).
