Continuity mistake: When Munson is on the bridge right before he backs up to tell Ishmale he passed the test, he has a vision in his mirror of his nasty landlord. When the vision ends he folds his mirror up, but the next shot when he's backing up, the mirror is back to it's original position.
Factual error: During the video montage after Roy, Claudia and Ishmael decide to go to Reno, Ish is seen sitting up in the back of the convertible. There should be a lot of wind but Ishmael's hair doesn't really move and he is even able to light his "smoking device" despite being in the open air. Toward the beginning of the scene Claudia and Ish are dancing in the back of the car and Claudia's hair is being blown around.
