Corrected entry: In the scene when Buck tries to call Chloe, on the caller ID it reads "Williams, Buck." It should read "Williams, Cameron" as that is his real personal name, Buck is only a nickname. The film makers put that probably because no one really calls him by his first name, but it is still a mistake.
Corrected entry: After Buck shows Ivy his apartment, look behind her when she says "Your phone is blinking." There is a crew member walking around in the background.
