Continuity mistake: When Pistachio is dressed a the cherryman, he spits his cherries at the henchman. He turns and spits one cherry, hitting one henchman right on the forehead. The henchman then falls backwards into the swimming pool, causing a huge splash. But in the very next shot, the water is totally still and the henchman seems to have disappeared from the pool.
Plot hole: When Pistachio and Jennifer go to the toy convention to find Bowman she says her name is Barbara, and Bowman invites her to his house. When Pistachio comes looking for her at the door (as the German Guy and the Snobby English Guy) he says he needs to talk to Jennifer Baker. Wouldn't he ask to see Barbara instead of Jennifer? Also Bowman knows her as Barbara and didn't say anything about him calling her Jennifer.
Continuity mistake: When Jennifer and Pistachio are looking at the photos in the restaurant, in a wide shot Pistachio holds a photo, and on the table in front of him there is an envelope, but no photos. But in the next close-up, Pistachio throws the photo he was holding onto a pile of photos on the table, which were not there in the previous wide shot.
Revealing mistake: When Pistachio grabs hold of the handles on the weight machine, they pull him forward and he goes flying into a wall, and his feet kick in and hit the wall making two holes. However as he flies towards the wall, you can see that the wall where he will make the holes has been weakened.
Continuity mistake: At the beginning, Fabrizzio is disguised as a woman. When he gets in the getaway van with the grandfather, they are in front of Bowman's mansion. When Fabrizzio takes off his disguise, look in the back window. It shows that they are on the road. When the van is driving away, they are still in front of the mansion.
