Here is a list of curious facts about the movie and some interesting details to look for the next time you watch it!

• The mall where Marty meets Doc Brown for their time travel experiment is called "Twin Pines Mall". Dr. Brown comments that old farmer Peabody used to own that land, and he grew pines there. When Marty goes back in time, he runs over and knocks down a pine tree on the Peabody's property. When he comes back to the mall at the end of the film, it is called "Lone Pine Mall".
  
• Eric Stoltz was originally cast as Marty McFly, but he didn't act enough like a teenager so he was changed for Michael J. Fox. In addition, his costume was completely recreated.
  
• The device in Doc Brown's lab in which Marty plugs his guitar has a label "CRM-114", which was the name of the message decoder on the B-52 in "Dr. Strangelove", and also the serial number of the Jupiter explorer in "2001: A Space Odyssey", both directed by Stanley Kubrick.
  
• The device originally considered to be used as the time machine was a refrigerator. Later in an interview, Director Robert Zemeckis said that the idea was not taken into account because he and Steven Spielberg did not want children climbing into refrigerators and getting trapped inside.
  
• The "Mr. Fusion Home Energy Converter", which is set up on the DeLorean when Doc returns from the future, was made from a Krups coffee grinder, among other things.
  
• When Marty goes back to 1985, he finds a beggar on a bench. He calls him "Red". He was "Red Thomas", the mayor in 1955.
  
• The radio in Marty's room plays "Back in Time", by Huey Lewis and the News, who wrote and performed some songs for the film. Also, a poster for their "Sports" album is visible on the wall of Marty's bedroom when Doc calls and wakes him.
  
• The "main street" used in this movie is the same one used in Gremlins.
  
• The theatre in 1955 is showing "A Boy's Life" (the working title for Steven Spielberg's E.T.), and "Watch the Skies" (the working title for Spielberg's Close Encounters of the Third Kind).
  
• According to the script, Marty was never supposed to bang his head on the door of the DeLorean. This was improvised during filming when the door mechanism became faulty.
  
• The newscaster on TV in the opening sequence is 'Deborah Harmon' (qv), who appeared in director Robert Zemeckis' Used Cars (1980).

Here are some deleted scenes (which fans like me hope to see on a collector's edition DVD) which were cut out from the final film:

• There is a part in which Lorraine says that when she grows up she will let her kids do anything they want.
  
• A scene where Marty decides to peek in a class in 1955 and sees his mother cheating on a test.
  
• In 1985 Doc put a suicase into the DeLorean trunk at the Twin Pines Mall. There was a scene in which 1955 Doc looks through the contents of that suitcase, picks up the hair dryer and asks "What's this?" "A hair dryer," Marty replies. Doc shakes his head and says, "A hair dryer? Don't they have towels in the future?" However, the scene was cut from the final film for time.
