Forrest Gump (1994)

Revealing mistake: While Forrest is playing the Chinese ping pong player, the camera shows him returning powerful volleys with ease. During one of these returns, his hand and arm bend at an unnatural angle due to the CGI graphics changing a forehand shot to a backhand shot.

Continuity mistake: The first time that Forrest runs across the football field, a front view of the coach's head shows him following Forrest without moving his head, coach just moves his eyes. But a back view of the coach's head shows the head moving, following Forrest's movement. Back to the front view and the head is still. (00:20:30)

Continuity mistake: Young Forrest's foot gets trapped in a sewer with a bunch of leaves around. When the angle changes the leaves are gone.

Deliberate mistake: In the scene where Forrest is describing his heritage, the clip of KKK on horses is taken from The Birth of a Nation. In this clip, you can see tire tracks on the dirt road well before automobiles were supposed to be in existence. Robert Zemeckis decided to leave this mistake in to perfectly match the clip to the original movie.

Continuity mistake: When Forrest lifts Lt. Dan to carry him out of the jungle, there is a pack slung over Lt. Dan's left shoulder. When the shot changes to Forrest carrying him over his shoulder the pack has disappeared, without time for it to have fallen off. Notice, this pack is separate from Lt. Dan's large field pack, which Forrest does unbuckle before he lifts him onto his shoulder.

Factual error: In the scene where Jenny is snorting coke, "Get Down Tonight" was playing, which came out in 1975. Then we cut to Hurricane Carmen, which hit in 1974. (02:25:00)

Continuity mistake: When Lt. Dan gets lifted off the bed by the male nurse, the handle he was holding on to disappears when the camera cuts to Forrest - it was so low that it should be in the picture. (00:55:30)

Factual error: We've already seen George Wallace on the school steps in one of the scenes where Forest is inserted into the footage, and this happened in June of 1963. Then it shows an All-American team meeting with JFK but that was created in December. But there was no way JFK would have been there as he was assassinated the previous month.

Continuity mistake: When young Forrest goes to young Jenny's house and he finds her in the backyard, they run away from the back of the house to get away from her drunken father. They kneel down in a patch of corn and pray to turn into birds and fly away. The camera then pans up over the corn and you can see that they are in the corn field in front and just to the side of the house, not the back of the house. (00:17:35)

Continuity mistake: After Forrest gets his medal he meets Jenny at the anti-war demonstration. When she goes to the bus to leave they are standing talking. In one shot his medal is tucked inside his jacket, but in the next shot (right before he takes his medal off) it is on the outside of his jacket. (01:09:15)

Continuity mistake: When the platoon is walking down the trail and he says they are always looking for a man named Charlie, he has a pack of matches in his helmet from his rations. When they get on their feet, he has a pack of napkins next to the matches. (00:44:15)

Continuity mistake: When Forrest sees Lt. Dan again after buying the shrimp boat, he dives off the boat and you see the boat going to the right, but after chatting for a short while they see the boat going in the opposite direction and crash into the pier. Even if it somehow turned itself around, it would would take longer than that.

Continuity mistake: In the scene just after Jenny shows up while Forrest is mowing his yard, Forrest and Jenny are walking and they happen upon Jenny's old house, where she lived with her father. She starts out by throwing her shoes, which she is carrying in her hand, at the house. The shot changes to view her from behind as she is throwing rocks, and she is standing on or just in front of a patch of grass in the driveway. As the shots change from in front to behind her, her position in the driveway has moved back from her original position, which is farther from the house by several feet, and when she finally collapses to the ground in tears, the patches of grass in the driveway have disappeared.

Continuity mistake: When the school principal shows the poster with the IQ requirements for regular schooling to Forrest's mother, the grip on his pencil changes back and forth in shots from the front and from behind. (00:07:50)

Factual error: When Forrest is reading the letter from Apple Computer, Inc., the date at the top of the letter says September 23, 1975. However, Apple wasn't founded until April 1, 1976 and wasn't incorporated until January 1977. No way to get a letter from a company that doesn't even exist yet.

Continuity mistake: When Forrest stops running, the close-up on him shows a sunny road with no painted lines on. The rest of the angles are of a shadowy place with painted yellow lines. (01:53:10)

Continuity mistake: When Forrest gets hit by a stone and falls on the ground a red school book is lying on the ground next to him. When he gets up he doesn't pick it up, and when he runs away it's not on the ground either. (00:15:20)

Continuity mistake: Young Forrest is about to step in the bus. He says to the bus driver, "My name's Forrest, Forrest Gump." That moment we have a back view of the bus driver's head and she exhales a big puff of smoke. A split second after we cut back to a front view of her and there's no smoke, instead she immediately exhales the smoke again.

Continuity mistake: In the scene where Jenny is adjusting Forrest's tie before their wedding, a man wearing a brown jacket can be seen on the porch behind them. Then in the next shot when Forrest sees Lt. Dan approaching, the man is gone. (02:00:20)

Continuity mistake: Before young Forrest's foot gets trapped in the sewer, a black car in the back is moving towards him, and is about to make a right turn. Close-up on Forrest's foot and, when back to the wide angle, the same black car is further back again and repeats the previous movements.
