Continuity: At the end of the film when David Duchovny and Orlando Jones go up the ladder to squirt the Head and Shoulders into 'the hole', Orlando Jones gets sucked up into the alien and when he is pulled out he is covered in slime from head to toe, (including his glasses), as is David Duchovny. However, in the next shot of them going down the ladder there is no slime on them at all. In the next shot when they are standing at the bottom, while the truck pulls away, neither of them have much slime on them, and Orlando Jones' glasses are completely clean. The amount of slime they are covered in changes throughout the next few shots.
