This is one of my favorite movies, with Humphrey Bogart and Lauren Bacall. Here are the mistakes to keep an eye out for!

General Sternwood is the father of the 2 wayward daughters. His legs are supposedly paralyzed, but you can spot them moving.

Geiger's house is central to much of the story. Just where is it? When Marlowe first goes there, the mailbox says "AG Geiger 460". Apparently the 460 was just a sham though - when he calls in the problem, he says the house is at "7244 Laverne Terrace".

This movie actually comes in 2 versions - and they were shot a full year apart. One version was made, then because of the war it was delayed. Before it was really released, they redid many scenes. If you get the DVD version you get both versions, so watch them back to back to see the differences.

If you've seen other changes, be sure to let us know in our forums!
