Goofs

When Valerie, Candy, and the aliens stop at the club, there is bag of fast-food on the dashboard that wasn't there before. (A deleted scene explains it. In it, Mac extends his arm by feet to pick up the bag; Val asks if he can do that with any part of his body.)

When Valerie, Candy, and the aliens are driving down the street, Valerie says, "I can't believe this is happening", and Candy is putting on hairspray with one hand while her other hand is styling her hair. In the close-up shot of Candy's reply, she is holding a pink mirror and a hairspray bottle.

After her night with Mac, Valerie grabs her package of birth control pills. The number of pills in the package keeps changing in each shot.

When Valerie picks up Ted's LPs, the cover of one of his speakers is missing, but in the shot where Valerie is lying on the couch tossing them into the fire, both speakers have covers.

When Valerie is watching is TV, there is can of Minute Maid Orange Soda and an empty glass. When Valerie turns off the TV and answers the phone, the glass is half-filled with soda.

In the song at the beginning, it says "Eons since I had a date, another light year is too long to wait" implying light year is a measure of time rather than distance.

When Mac is first seen sleeping suspended in the stasis chamber at start of the film, the two wires that keep him "levitated" are visible.

As Zeebo is kissing Tanya, the device used to make his ears wiggle is briefly visible.

The fish skeletons Mac and Wiploc pull out of their mouths are much too large to have been inside the fish.

It is an obvious stuntman when Wiploc stands between the two Jeeps.

During the MTV scum scene, the crew and camera can be seen in the mirror as the actors come into the main room from the hallway.

When Valerie goes into the bathroom to destroy Ted's cologne with a golf club, the steadicam and operator can briefly been seen in a mirror behind the door.

When Valerie turns on the kitchen light with Ted's football in her hands, the shadow of a small fuzzy object can be seen waving around on the left side of the wall. (widescreen version only)
