Corrected entry: Martin Short is a lot smaller than Dennis Quaid, but when Martin puts on Dennis's jacket (to get the car keys when they escape the lab) the jacket fits Martin perfectly.
Corrected entry: Tuck inserts a clip in Jack's ear so that Jack can hear him. How is it then that when Tuck is transfered in to Lydia that she can hear him? Tuck never put any sort of clip in her.
Correction: She can't hear him, there's a fairly involved scene where Tuck has to play music at an extremely loud volume so Lydia will know that he's inside of her. This is the only way she knew he was inside her, he never actually spoke to her.
Corrected entry: In the scene where they are trying to recover Tuck, the lights go out. So why do they need a flashlight to look at a computer screen in the dark?
Correction: They don't. They need to see the keyboards.
Correction: Actually, you can tell the jacket is too big. While it doesn't hang off his arms, the sleeves are bunched up quite a bit.
