Early appearances of color: the red rose, after the encounter at Lover's Lane; pink bubblegum seen in the hallway at school;one girl's pink tongue;the red hearts of the cards in the bridge hand;the subtle green of the car in front of the diner;the jukebox in the diner becomes multicolored the guy in front of the jukebox combs his hair with a yellow comb Jennifer's red cherry on her shake in the diner;the pink cherry blossoms reflected in the side mirror of the car;the subtle green of the grass at Lover's Lane before it turns completely colorized.
Though many believe that the shot of Bud raising his arms up in triumph during a rainstorm is an homage to The Shawshank Redemption (1994), Gary Ross thought it was an original idea, and didn't realize the connection until after the film was released.
When Mary Sue is with her date at the restaurant and she leaves to go to the ladies room, her hair is styled differently than when she is inside the ladies room.
At the very end of the movie, George Parker and Betty Parker are sitting on a bench. The camera pans from George to Betty, then back to where George was sitting, and he "turns into" Mr. Johnson. If you look at Betty before the camera goes back to Mr. Johnson, you can see her bounce. This is from Mr. Johnson sitting down in George's place.
When Jennifer and David are fighting over the remote control before the Pleasantville Marathon starts at 6:30, they momentarily go to the Prevue Channel. The time shown on that channel is 1:16, not 6:30.
Won't Jennifers real mother wonder where her daughter is when she is gone for a long time?

We know that time works differently in Pleasantville, as it only took an hour for the story to unfold in "real life". At the end of the film, when David returns, we here the TV announcer say "And that concludes the first hour of our Pleasantville marathon".In the DVD commentary the director, Gary Ross, explains that a Pleasantville episode lasts for 30 minutes, but that each episode's storyline takes place over about a week. So if Jennifer spends three years in college, it will only equate to a long weekend in our time. Given that Jennifer was both popular and self-absorbed at the start of the film, it may not be out of character for her to disappear for a weekend.
