Ron Jeremy
Okay so this post is completely off-topic (assuming there's any one "topic" to be had here) but as I was reading FHM magazine this morning I found out that Ron Jeremy was an exta in the movie Ghostbusters (a reader wrote in swearing he'd seen Ron Jeremy in a freeze-frame). As it turns out, Ron Jeremy was indeed an extra but was so far off the screen he could only be seen in the widescreen theatrical version.

So, as that's a random fact I figured - why not look him up in IMDB? Turns out he's appeared in 955 different movies. It's kind of hard to tell if they are all porn but still, 955 movies?? A coworker said something to the effect of "see how many Jackie Chan has been in". So I checked. He's done a paltry 97 films. Miniscule by comparison.

In the FHM interview Ron Jeremy said that he plays extras all the time - sometimes up to 20 movies a year. For those directors hesitant to credit him as Ron Jeremy he goes by the name Ron Hiatt (among some 10 other pseudonyms).
