At the sex addiction meeting Julia's pantyhose change to leggings and back.
In the beginning after the guys realize they need half a million dollars and start brain storming on the dry erase board in almost every shot of that sequence the "R"s have changed how it is written in "murder".
While waiting for the freight train to pass, the direction of the train changes in the middle of the scene.
When Nick, Kurt and Dale meet "MF" Jones for the second time to buy the cellphone, his watch disappears from his left wrist between shots. In the scene when Nick, Kurt and Dale leave the bar in slow motion said watch is back on Nicks wrist. The scene where "MF" gives the watch back to Nick as requests right before the watch disappears (very hard to understand and subtitle is missing, but understandable in German) seems to be filmed but not in the movie.
Before entering her house for the sex meeting, Julia wears a miniskirt with tights underneath and high heels. When she lets her therapy group in, she is wearing some sort of leather leggings under the skirt. In the next scene she's back in her tights and high heels.
"Kidnaping" with one p is a legitimate alternate way to spell the word "kidnapping".
The Twitter hashtag #We'reNotRacist is all blue. But Twitter doesn't recognize apostrophes in hashtags, so all the characters after the first "e" should be black.
When Nick, Kurt, Dales, and Rex are driving in the car coming back from making the ransom call to Rex's father, crew equipment (orange ladders, black storage boxes) can be seen out the passenger car window as they drive down the street.
After Jason Bateman turns down Katy Perry's Roar the equipment can be seen on the left side of the screen.

Detective Hatcher asks Rex why he hasn't called the police with the phone in 'his' pants. He just found Rex 'bound' and gagged in the warehouse. That would explain that.
At the sex addiction meeting, as Julia was asking Nick to give the details about his sexual experience when he was fourteen at wrestling camp, "Roz" tried to tell Nick he didn't have to answer a question. Nick replies "Roz, shut your mouth". Nick hadn't been told anyone's name nor did Julia say her name in front of Nick.
