Continuity: When Trip passes out at the Wordfest, and he wakes up with Sarah standing over him, watch her hands. Every time they switch shots, her hands switch back and forth between holding a cigarette and a box of cigarettes, to her simply having her hands at her sides.

Revealing: Michael Douglas pulls up to the curb to park his car. When he opens his door, it hits a fire hydrant, which moves! This is very easy to spot.
