- Marty: "It's like we're in Hell or something!"
- Doc: "No, it's Hill Valley, although I can't imagine Hell being much worse."
- — Marty McFly and Emmett Brown in 1985A
"Hell Valley" was an alternate name for Hill Valley in the nightmarish alternate timeline where Biff Tannen had used the Grays Sports Almanac to amass a fortune by successfully betting on sporting events and now controlled the city, turning it into a crime-infested place where criminals and biker gangs made their home.
The greeting sign was defaced with spray paint and crudely altered to this name, as well as having been riddled with bullet holes and knocked to the ground.
Behind the scenes
- 1985A was the only alternate timeline that was named on-screen — a designation that was given by Doc as part of a diagram drawn on a blackboard in his trashed lab to explain to Marty about the timeline having been skewed.
- Tom Wilson, the actor who portrayed Biff in the Back to the Future trilogy, stated that this timeline was referred to as "Biffhorrific" by the cast and crew of Back to the Future Part II.
- This timeline also encompasses 1955B, 1970A, 1971A, 1972A, 1979A, and 2015C.
