The O.C. (2003) - 9 major mistakes

Continuity: Ryan and Theresa are walking along the beach with ice creams. The amount of ice cream changes between shots. This is especially noticeable with Theresa's ice cream.

Continuity: In Series 2, Episode 'The SnOC', we see Zach punching Seth with his right fist. However, when Summer gives him some ice, he covers his left fist with it (which is now bruised and swollen).

Continuity: When Ryan is lighting Marissa's cigarette with his, at the start of the shot it's full, then the shot goes to Ryan and it's still full. But then the shot goes to Marissa and if you look at Ryan's cigarette you can see it is almost all gone. Then the shot goes to Ryan and the cigarette is full again.

Deliberate "mistake": Lindsay is not at Caleb's funeral in the last episode of season 2, "The Dearly Beloved". It's unlikely that she would have missed it - she is still on good terms with him and he is her father, the only reason she left was to be with her mother, not because she didn't love Caleb.Obviously they didn't want to create another drama with having Lindsay there while they had to focus on the important story-lines - Caleb's death, Kirsten's drinking and Marissa shooting Trey.

Continuity: In season two, episode "The Return of the Nana", Marissa's arms change position repeatedly while she and Trey are down at the beach. Also, her bag appears with her, even though she left the apartment without it.

Continuity: When Marissa is dumped on the driveway by Summer and Holly, Ryan first sees her there her left arm is across her chest with her elbow sticking up. The next shot of Marissa her ams are straight and spread out, and the next they are close by her sides, which is impossible for her to have moved them herself as she is unconscious.

Continuity: Season 4 - Episode 8 - The Earth Girls Are Easy - When Kaitlin is at the party, talking to Bullit, her strand of hair changes from hanging over her eye to hanging down next to it, without her moving her hands or head to displace it.

Continuity: In the morning when Seth goes into the kitchen where his parents are, he reaches into the cupboard to get a bowl. However, in the next shot he now has a box of cereal.

Continuity: Early in the episode, Alex tells Seth that the night of the Killers concert is her night off. (She works at The Bait Shop, the concert venue.) At the end of the episode, Alex is paying The Killers, as if she were the manager on duty.
