Drugstore Cowboy (1989)

Factual error: The motel's billboard advertised HBO, which did not exist in 1971 when the movie was set.

Factual error: In the final flashback scene, which was no later than 1971 because Nadine was still alive, the Ford van is a distinctive style not introduced until 1975.

Factual error: The movie is set in 1971, but a fire extinguisher with modern pictorial labels can be seen when the detective is dusting for fingerprints in the drugstore.

Trivia: There is a scene where we get a look at the neighborhood around Bob's house. We see an elderly lady sweeping her front porch, glancing suspiciously at Bob. That lady is Ruthie, and she owned the house on North Greenwich Avenue used for most of the interior shots. The porch she is sweeping is at the house across the street from hers.

Rick: Jesus, Bob, you never told us anything about not mentioning dogs.
Bob: The reason nobody mentioned dogs, Rick, is that to mention the dog would have been a hex in itself.
Rick: All right, well, now we are on the subject, are there an other stupid things we aren't supposed to mention that will affect our future?

Bob: You just put a 30 day hex on us, that's what you did. Our luck just flew out the window for the next thirty days.

Bob: Father Murphy? Hey Tom.
Tom the Priest: Well well. Bad Bobby Hughes. Imagine seeing you here after all these years.
Bob: You live here too?
Tom the Priest: I have nowhere else to go. There is no demand in the priesthood for elderly drug addicts.
