The scene where Jake follows the Russian to a JFK campaign speech utilized actual audio from the speech JFK gave that day, in that location. The speech and location was heavily photographed in 1960, and was recreated near perfectly.
The opening credits changed slightly every week, reflecting Jake's changes to the time line and/or foreshadowing events in the episode.
The story that Jake tells Mimi is taken from the films The Godfather: Part II (1974) and The Godfather: Part III (1990).
In the first episode Jake (James Franco) makes a reference to Stephen King's Misery (1990), "I'm his number one fan!"
The car that Sadie Dunhill gets into during the first episode is the same red 1958 Plymouth Fury that the movie and book Christine (1983) were based on. Plymouth did not make a red Fury in 1958.
The scenes involving the diner were shot in Guelph, Ontario, Canada at the corner of Oliver and Huron Street. A fake diner was constructed there.

Back to the Future Part II (1989) premiered on November 22, 1989, First Contact (1996) premiered on November 22, 1996, and Doctor Who (1963) premiered the day after, on November 23, 1963, although it didn't get much of an audience, on account of the Kennedy assassination the day before.
In the final episode 'Redrum' is painted on a wall inside the book depository, a reference to The Shining.
Annette O'Toole (Edna Price, episode 2) played Beverly Marsh in 1990's Stephen King's It (1990). In the Book 11.22.63 Jake meets Beverly and Richie from It in Derry which in the series is replaced by Holden.

James Franco says "so good" when asked how the pie tastes, which is a Spider-Man 3 reference of the same dialogue
The Hertz ID created by Al and given to Jake in episode 1 is a reference to the Hertz Rent-A-Car sign atop the Texas school book depository at the time of the assassination. For some reason the producers didn't recreate the sign atop the TSBD for the series.
Another one of the many references to other Stephen King books and movies: one of the stores visible on the Main Street in Lisbon, Maine, is Blue Ribbon Laundry--also the name of the business where Margaret White (mother of Carrie) worked in the novel Carrie.
James Franco is a producer for this series in addition to playing the lead character, Epping.
Several scenes, including the car yard, diner and men's clothing store, were shot in Dunnville, Ontario.
