I was hearing on the radio that Jon Heder (Napoleon Dynamite) died of a car crash. I've been reading sources (like IMDB) saying that this rumor has been spread for 2 weeks, but that radio is now saying that it's true.

Do you believe them?

Saw him on Letterman not TOO long ago, but not within the time frame .... so I have no idea.

First I have heard of it.

No, I don't necessarily believe it, especially if the rumors were circulating for two weeks. It's VERY easy for some yo-yo on a message board (not this one, more like on IMDB) to say Jon Heder died in a car crash, and for people to believe him. Take it for what it's worth, until an actual news station or online news website says so. Personally, I hope it's not true at all. While I'm quite vocal about my disdain for the film, Heder was the only main reason why I could tolerate the film, and I'd like to see him do other film projects.
