Continuity: When Michael is dancing in the nightclub, wearing a trench-coat, he spins around in a circle and his trench-coat floats up a little, and there are no wings available, but then immediately following the spin, his wing tips are sticking out from the bottom of the trench-coat.
Continuity: After the bullfight, the reporter is shown with his tie over his left shoulder, when shot form the front. From behind, the tie is not over his shoulder.
Miscellaneous: When the group first leaves Pansy's house, and they're driving down the highway on their way back to Chicago, the rear-view mirror appears and disappears, depending on the shot. Views from inside the car show the mirror. Views looking in from the outside reveal the mirror is missing.
Miscellaneous: At Joe's, the first restaurant the group stops at, the waitress brings the food and, within minutes, when Micheal gets up to dance, the waitress comes back and takes Dorothy's plate without her having eaten anything from it. The waitress then sets down a cup of coffee.
Errors made by characters (possibly deliberate errors by the filmmakers): Michael changes hands when he's eating. At Pansy's, he eats his cereal with his left hand, but at Brown's, he eats his pie with his right hand.
Miscellaneous: When Michael is sitting outside of Brown's Motel, talking to Sparky, big rolls of hay can be seen relatively close to them. In later shots, the hay is in a field much farther off in the distance.
Audio/visual unsynchronized: When Michael is in the back of the car, counting down the ten seconds before the tire blows, the audio is saying "seven hippopotamus, six hippopotamus..." but Michael's mouth isn't.
Crew or equipment visible: In the scene where Michael is bringing Sparky back to life you can see a glimpse of the wire extended his left wing.
Continuity: When Michael is in the field after Sparky has been run down by a truck and he is facing Dorothy, Frank and Huey, the sun is on right hand side and is bright. When the shot goes back to the other characters, they are facing Michael and the sun is also on their right hand side and is obviously lower in the sky.
Errors in geography: When all of them are driving to downtown Chicago to see the Sears Tower, there's a shot of the car driving down the highway. Then in the next scene you see them driving down another highway with the lake on the left, and the John Hancock Tower in front of them. This is impossible because the first highway is I-90 and the other highway is Lake Shore Drive (U.S. Route 41). There is no direct way to go from I-90 to U.S. 41.
Continuity: In the opening scene of the movie, there is a flag seen outside of the First Commerce Bank. When the shot is further away, there is no longer a flag.
