When Dr. Bellows tells Tony he wants to show him a tape made several weeks ago, Tony replies that he doesn't remember making any tape even though he hasn't seen his double in the tape yet.
In the shot of the earthquake in the kitchen, Tony falls against the countertop extension pushing it and the rest of the set several inches to the left. There is also nothing next to the washer and dryer, but when Tony looks in to the kitchen after Jeannie produces dinner, there is a table and chairs set up in that space.
There are four instances of dialogue being drop dubbed (post production), that are different from what the speaker originally said, (judging by what their lips say).
6 minutes in, when Tony is on the plane before jumping out, he says to the two air police officers "There's one thing I know: we're going fast", but his lips say something else.
Three minutes later, after Tony jumps out, the two air officers are talking. The first one looking down out the door says "Sure is a beautiful place. I'd love to take a vacation there", but during the words "sure is a beaut..." his lips say something else. The tag end of the word "beautiful" (...iful) followed by "place" are on his lips but out of sync (ahead of the sound); obviously he originally said something shorter in place of "sure is a beaut...". His second sentence is intact; no dubbing mismatch. But the second air officer's immediate response "You'll wanna take at least a week", is completely different from what his lips say.
17 minutes in, when Tony is in the lab and tastes the food, he says "Veal cutlet. My favorite", but his lips say something completely different.

On the cut to the clock in Dr. Bellows's office that says 8:01, the electronic sound effects of Tony's location carry over from the previous scene.
The real Tony is sent to a Mediterranean Island. Roger says Tony is in the Southern Hemisphere. It's either a writer error or Bill Daily forgot his line, because the entire Mediterranean is in the Northern Hemisphere.
