Continuity mistake: In an early scene Jack and Collette sit in a bar. While he is drinking a martini she tells him that he is the father of her son. He is so shocked by the news that he practically finishes the entire drink, leaving only a little bit and the olive in the glass when he sets it down. The camera swings to another angle and the martini is full again and after the camera changes angles a few more times, each showing a full glass, it finally goes back to the original angle where the glass is once again almost empty.
Continuity mistake: Shortly after Dale drives off in Jack's Jaguar he picks up a lady whose car has broken down. After they get into the Jaguar they introduce themselves, smiling at each other. Then they both turn ahead as Dale is about to drive off, but when the camera angle changes they are again talking and smiling at each other.
Continuity mistake: After Jack and Dale take Scotty home they sit on the sofa looking at a photo album. Jack says "look at this little cowboy hat.". Then the camera cuts to the album and there are two big photographs of a bare-headed Scotty. Then we see Dale turning the page, and there's again a different picture on the page we can see.
