Continuity mistake: Jack and Betsy arrive at Bally's in Vegas and it is dark. After checking in and going to their hotel room, it is daylight outside. There is no evidence of them doing anything between check-in and going to their room.
Continuity mistake: When Jack finally locates Betsy (in Hawaii) and is calling out to her, Tommy spots him and tackles him to the ground. As the hotel security is pulling them apart one can see visible stains on the knees of Jack's pants (presumably from damp grass). A moment later as Jack is getting in the police car his pants are spotless.
Continuity mistake: As Betsy is dressing for the wedding and while she is discussing her "cold feet" with Tommy in the lobby, the left side of her hair goes from having some strands loosely pinned back to hanging down.
