Continuity mistake: When blood gushes out of the bullet wound during 05's introduction, in the first slo-mo the squirt goes diagonally across her eye. Then all that is left is a horizontal streak from the mouth. It is implied that between cuts she fit her glove by biting it, so the inconsistency can be explained (even if just a rushed wipe would hardly clean her completely). The real mistakes are: 1 - she has a dotted streak of blood before and after, entirely inconsistent with those close-ups, and 2 - when Ryan Reynolds and Dave Franco are talking about the 'squirting', you can see in the background Adria Arjona's face is totally clean.

Visible crew/equipment: After 5's blood facial, the gang is driving fast through Florence's small streets. Look out for the moment when Dave Franco says "That's my problem, I'm just getting warmed up." He does a right turn, and we are shown a POV of the villains shooting. Mounted on the car, you can see an additional GoPro-like mini-camera. (00:08:20)
Continuity mistake: During the "Baby! Baby!" scene, multiple flubs happen. To name a few; in the POV shot they are this close to hitting the woman with the baby, but she is at a greater distance right after; in one shot her bag is on the ground and not on her shoulder; two pigeons fly in front of her, but in another take one even connects with her hair; people watching horrified by the monument and in the piazza itself appear and disappear between shots, Ryan Reynolds is sticking his head out in close-ups but is nowhere to be seen in the other angles. Finally, plenty of skidmarks are already visible on the asphalt. (00:06:30)
Trivia: During one epic car crash near the start, just after the shooter gets taken out by the digger, if you know what to look for you can see Ryan Reynolds in the background, filming a post/advert for social media. Not a mistake, because it's just a tiny figure at the back of shot, but pairing the film and the post together it's fun to look for. (00:14:42)
