Revealing mistake: In the scene near the end, when the two cops are fighting in the "out of control" bi-plane, the plane is seen looping and twisting as the "pilot" Tack has jumped out. However, in the side-on view of them fighting you can see a new pilot trying desperately to stay out of shot, but failing due to the g-forces he is under while the plane moves around.

Revealing mistake: When Sweet Chuck is sitting on a bench in the gym reading a paper, the big heavy comes down and sits next to him. Sweet Chuck goes flying up in the air a second before the big guy sits down.
Continuity mistake: At the end of the movie, the two balloons are in the air. As one of them goes down to land, we see a shot with balloons on the ground. In the next shot, one of them is still up and flying.
Continuity mistake: At the end of the movie when Tackleberry glides down the balloon you can see that the color/shape of the balloon changes between the closeup and far off shots.
Continuity mistake: In the middle of the film when the guys are playing basketball, Hightower slams the ball in the ground making a huge crack in the pavement. But when Proctor enters the basketball yard the crack is much smaller.
Visible crew/equipment: In the skateboarding scene there is a close up shot of the guy with red pants on. As he skates off the screen you can see a shadow of what looks like the camera man following him. It can't be a shadow of another skateboarder, because they were all skating ahead of the guy in the red pants.
