The concept of fake movies is a regular gag in films and TV shows about filmmaking and fictional Hollywood figures. Trailers for these non-existent works are especially fun, more so now that they can go viral on the Internet. But not all fake movies are conceived as parodies within real movies like "Tropic Thunder" and "Funny People." Sometimes they're a method of deception, positively or negatively, for some actual real-world purpose. The new film "Argo,"
for instance, depicts the true story of a rescue mission to free hostages in Iran, which involved a pretend production of sci-fi movie as a cover.
Other real-life fake movies have come before and after the one seen in "Argo," whether they were the work of governments, con men, marketing companies or sneaky romantics. As a bonus, one of the following examples even has a direct tie to the new movie, which was directed by and stars Ben Affleck. VIDEOS/PHOTOS:
