Continuity mistake: Kol shouts, "Stop the car!" Adam slams on the brakes from a cruising speed, yet miraculously, the car is bumper-to-bumper with a parked red SUV. When Kol gets back into Adam's car, the red SUV should be visible. However, outside of the windshield, there is a white blur. A car drives close by on a perpendicular road that wasn't there before Adam stopped. (00:15:48 - 00:16:20)
Factual error: Rose's legs were paralyzed, but when she was dragging herself on the floor, she occasionally used her feet to help propel her body forward (and moved her feet downward) - something she would not be able to do if her legs were paralyzed. (00:33:40)
Continuity mistake: In the very last scene when Bo is hugging Stanley before the game it reveals his "Never Back Down" tree tattoo on his lower left arm. Yet right after in the closing credits and presumably depicting that same game it showed his left arm after taking a shot with the tattoo removed.
Factual error: Twice during the movie, streetlights are visible: once when lady Russell informs Anne of Wentworth's engagements, and once while Anne is running after Wentworth. (Streetlights, lit by gas, were indeed conceived during the regency period - but they were experimental curiosities, and certainly not yet installed nationwide).
Continuity mistake: Francis pistol-whipped Leonard and - although there initially was no red mark - a red mark could be seen when Leonard attended to Richie's wound. Not long afterwards, the red mark was gone (but should have still been there). (00:21:35 - 00:35:06)
Continuity mistake: The bottle of beer on the bar in front of Everett disappears in one shot but re-appears. Also, depending on the camera's angle, Everett either has his right hand holding onto the edge of the bar or is below the bar (out of sight). (00:04:25 - 00:40:14)
Continuity mistake: Angel had her hands very close to (almost touching) the towel, but when the camera shifted to a front view of her, the towel was a couple feet away from her hands. Also, the peppers that were to the right of her hands were suddenly in front of them (moved with the celery to her left). (02:00:00)
Plot hole: After sending the offensive message to his students, Charlie got on-line with them (within hours or the same day?) and said, "Well, your complaints have been heard. I've been replaced..." IF an on-line college instructor could be terminated and replaced as quickly as Charlie was, it would follow that he would no longer be able to access the on-line course to communicate with the students like he did. (01:39:55)
Suggested correction: I think this is based on too much assumption. Any sort-of ban would likely be entire dependent on whatever system they're using for their online class. And it's entirely plausible he'd still be able to access his account mere hours later, even if the call has already been made to replace him.
I worked for the Defence department in Australia and it was a running gag that eighteen months after I had left my online access to my account was still open, allowing me access to highly classified documentation, including emails. Mistakes happen.
