Continuity mistake: When the police show up at the airstrip to arrest Gilly, Dig is trying to eat his stash and the mouthpiece on his headset goes from in front of his face to under his chin between shots.
Other mistake: After the failed marriage between Jo and Jack, there is a shot of a cliff. Notice that the clouds moving overhead simply disappear into thin air.
Continuity mistake: When Heather Graham gets in her car to go find Gilly, the first shot shows her reaching back to put on her seat belt, the camera cuts to her mom and then back to her, she does not have her seat belt on in this shot. Then the camera flashes back to her mom and then back to her, she now has her seat belt on.
