Visible crew/equipment: In the beginning where the camera is following some of the characters to appear later in the film, when we see the Harii Krishna guys a cameraman and a camera on a dolly track are reflected in a shadow on them for a few seconds. (00:02:30)
Trivia: Director Jim Abrahams has two roles in this movie. The first role was that of the bicycle rider that yells back at Kramer after Kramer hits him on the road. He also plays a role as a solicitor at the airport. He is the one who pauses after seeing how Kramer is treating the other solictors. (00:52:10 - 00:54:55)
Visible crew/equipment: At the point where Striker is walking through the tunnel to board the plane near the beginning, for a split second, one can see a section of cable lying on the floor and a crewmember off to the side. (00:04:35)
Continuity mistake: After you see all the newspapers talking about the plane, and when you see the drummer on TV who speaks by drum tones, when the drums are handed to him the ends of the sticks are round, but when he looks to HIS left, after the camera changes position, they're not round anymore. (01:04:45)
Revealing mistake: When the Girl Scout crashes into the jukebox, you can see the lights turn on before she hits it. (00:17:10)
Revealing mistake: In the flashback scene in the bar, one of the girl scouts slams the other girl scout onto the floor and one can see the mat that the girl lands on. It had been covered in dirt or dust but when the girl lands it is swept away and you can see one of the corners of the mat. (00:16:40)
Other mistake: When Johnny reads in the folded newspaper, 'There's a sale at Penny's!', the viewer can read the headlines right way up - which means, from his side, he is holding the paper upside down.
