The phone

I think the beginning and end of this film is a bit of a problem. When Leona is about to hang up the phone after reaching the busy signal at Henry's office she manages to hear the connection of the two plotters which allows her to listen in to the phone. She gets the full conversation but then it conveniently disconnects when they are about to discuss the address. Then at the end, someone has picked up the extension in the kitchen yet a few moments later she is able to receive the final call. They could have just put that part into the last call. I realize both these things can be just explained with 'It's a movie' but I thought those parts weren't well done.

Also I noticed that in the flashback scene, while Barbara is in college (ha ha), when she is in the car with Henry, he is driving on the right side of the car. I thought they would have mentioned it in the Goofs section.
