Continuity mistake: Some figurines on Lidya's nightstand changed positions near the start. The rabbit was moved closer to the front, then back. The blue object was moved back a couple inches. (00:03:15 - 00:03:58)
Plot hole: When Rupert brought his "secret pen pal" letters from Hollywood movie star John to school, they were stolen by some classmate bullies (and apparently never recovered). Rupert would have been around age 11 (possibly 12) at the time. It is inconceivable that a child could recall enough details from the letters to write a book about them 10 years later.
Continuity mistake: Felix on his skate jumps over a rolled-up rug some movers are carrying in the middle of the street. He jumps and the street is in the shade, he skates away and the street is full of sunshine. (00:01:30)
Continuity mistake: In the opening scene with the skype call, Mia's hair is in front/behind her shoulders depending on the camera angle, with no logic. (00:00:55)
Revealing mistake: Most of the car scenes entailed rain on the windows even though it otherwise had not been and was not raining, indicating the scenes were filmed on a rainy day. For example: Mary driving home; picking up Todd to go to the funeral; driving home from the church; driving back from rock climbing; and, Faith's car when she got to Luke's house. (00:17:35 - 01:34:12)
Continuity mistake: When Phil heads to the Puppet Pleasure place early in the film, the positions of the shadows change around the vehicle parked out front in the close up, revealing the time laps between filming each shot. (00:06:30)
Factual error: Michael boards a commuter train at Grand Central, which then stops at subway stations at 68th Street, 86th Street, and 110th Street along Lexington Avenue. This is impossible.
Visible crew/equipment: During the opening while Ray and Maggie are driving at night, you can see the lighting equipment for the green screen reflected in Ray's glasses. And throughout the entire movie, these green screens and other production lights can be seen reflected in his glasses in several different scenes. (00:04:00)
Continuity mistake: The clothes Tyler and Kassi were wearing at Kassi's house were not the same when Kassi came to dinner that day at the Burnside's house. It seems unlikely that BOTH would change clothes before dinner. (00:31:49 - 00:32:40)
Suggested correction: Apparently they did. It was probably Tyler's idea, presenting Kassi in the best possible light to assuage suspicion and maintain his image as a good Christian Boy Scout.
Continuity mistake: LA Bar after their arrival. Tim Roth asks Uma Thurman why Irina hates her so much. Her glass is on the table then in front of her lips, in a sudden change. (00:19:55)
Continuity mistake: The Nurse just told Waikiki about his brother's addiction. She receives a call when she is outside the room. In close-up she is holding the tablet with just her right hand, lowering the left. Next shot and she is holding it with both hands. (00:20:10)
Continuity mistake: Jeffrey downs all his whiskey, but in the following shot his glass is still half empty. (01:35:50)
Continuity mistake: Right at the start after they dock with the escape pod, three people enter and Kanelo calls out for Franklin. The guy behind Kanelo shines his flashlight to the right of the screen, but when it cuts to a close up of him, suddenly he's shining it towards the left of the screen. (00:03:15)
Revealing mistake: When the doctor with the satellite phone runs to the car, he is being chased by another member of the team, and of course the graboid. Look ahead of the graboid. The path it will take is visible.
Continuity mistake: In the basement when the girls are talking, one mentions to Chloe that she and Carl would make an adorable couple. Chloe's left arm is stretched up above her head in this shot. But in the next shot when she corrects her on the guy's name, it's suddenly down by her lap. (00:06:10)
Continuity mistake: The position of Don's baseball cap on the table changes two times. Initially, the cap is near the corner of the table with the visor and letter "P" roughly parallel to the front of his body. After he pours beer into his glass, the visor is angled more toward the corner of the table (even though the camera appears to pan around it). When Don brings Mike back to the table, the cap visor is pointed toward Don and is at a differently angle (more parallel to the front of his body again). (00:00:09 - 00:01:47)
Other mistake: While "dead" Mike is bent over his car's engine, his left leg moves. (00:32:40)
Continuity mistake: At his diner, Bibbo is telling Clark and Lois a story about Superman and he has some menus tucked under his arm. In the wide shot they appears brownish red, but when it cuts to a close up it turns white and light appears on it. Also Lois has her arms down at her sides first, but then in the close up she's suddenly turned towards Bibbo with one arm on the table and the other propped up by her chin. (00:46:10)
Continuity mistake: When Jason lunges at Batman with his knife, there is a pile of garbage by the wall where he lands. In the first shot the barrel by the garbage is wooden. But in the next shot it's suddenly a metal barrel/drum. It then changes back to a wooden barrel again. (00:04:20)
Continuity mistake: When Nick Cage and the woman get to her place and start to make out, he takes her bra off, leaving her bare chested as he fondles her. It cuts to a different angle as they are kissing and suddenly her bra is back on again, only to be gone in the following shot.
