Continuity mistake: In the opening scene, Mort closes the door of his jeep before he goes into the hotel room. You can hear the sound of the door closing and it's visible in the rearview-mirror. As the camera moves out of the room, the jeep door is completely open. (00:02:05)
Suggested correction: The door just didn't actually catch. I've had cars like that, especially during the winter.
Given that we see it stay closed for almost 4 seconds and hear it catch, it's a valid mistake.
If you've ever lived where it snows a lot, you'd know that door catches accumulate moisture (ice) and can open slowly, as it did in this case.

At the hand-off, when he places the drink on the tray, there are no vials in the glass - there is no ice blocking them from view, just a skewer holding a maraschino cherry, a wedge of lemon, and a straw - no vials. Even Jack can't make the two vials invisible. (01:23:40)
