In the scene when Vince and Mandy are outside talking before the "Aquaman" press conference, when Mandy says the line "is this going to be a problem for us to work together?", the front shot of her shows her folding her arms. In the very next shot from behind Mandy, her arms aren't folded.
At the start of the show, Ari and the boys do not get into the U2 show. At the end of the show Ari calls up Drama and tells him, U2 added another show so that they could go. Since this took place during the Vertigo tour, the band had all their extra dates sold in advance before the tour started. They did not add additional shows while already on tour. It is perhaps intended, that Ari meant to say this to Drama who may not have been aware that there was another show that they could attend.
