Revealing mistake: When the target's iPhone rings and Christopher Chance answers it, he swipes his finger across the bottom of the screen, which is the regular gesture to answer a call on the iPhone. Trouble is that we see the screen at the time, and it's not showing an incoming call, just some sort of list - he swipes his finger over nothing of any significance at all.
Lightspeed - S5-E8
Revealing mistake: When the HIVE Five exit the museum and are intercepted by Kid Flash, Mammoth loses both his pants and the artifacts he has before KF whizzes past him. It's best seen in slow motion; at normal speed this mistake is hard to catch.
Revealing mistake: About 20 minutes in, the cops have a newspaper with the headline about the two guys they killed. They turn to page two which has a story about the next guy they are planning to kill. If you look at the picture, it is glued onto the story page. The left side is lifted. The actor must have been hired after the printing.
