Continuity mistake: Bruce and Selina sneak away from the party while Bruce's neglected childhood friend fetches the drink. The bottles on the shelves behind the counter change between shots when he goes "Seriously? Both of them?" It's like a portion of the leftmost shelf has been sliced off for the close-up. (00:05:00)
The Riddler: Riddle me this - "The less of me you have, the more I am worth " what am I? Answer - A Friend.
Trivia: Peyton List voices Batgirl. Peyton List also voices Poison Ivy. This is not the same person getting credited twice. It's two different people. Normally the SAG doesn't allow two living members to have the same name, but they accidentally missed the younger Peyton List (Batgirl). The SAG should have made the younger List use a middle initial or stage name. Incidentally, the younger List got her start in an uncredited role in an episode of "As the World Turns" which also featured the older List.
