Characters in movies generally live life exactly like us regular folk do. They eat, they drink, they fight robots (okay, scrap that last one) but one thing they don't do enough of is talk about movies.
If you were confronted with a zombie, chances are you'd liken the situation to that bit in Dawn of the Dead where someone was confronted with a zombie. That's if you're not being ripped apart of course. Certain films such as the Scream series took this idea and ran with it but, on the whole, it's not quite as commonplace as you'd think.
Here's a look at 50 examples of films that talk about films. The rule being that the title of the film has to be mentioned in the dialogue. If you can think of more then please add to the list at the bottom.
