Tom Hanks is OBVIOUSLY Locke's biological father.

Doug Flutie on Lost?!?

Wow, I can't wait!!!!!

IMDb isn't _quite_ on the wikipedia model. It's true that anyone can submit information, but it does have to pass through a human before appearing on the site. (Some aspects of IMDb do have wiki properties, like the FAQ, but cast lists don't.)

It doesn't mean things don't slip through, _especially_ in unaired things. Contrary to popular belief, employees at IMDb don't generally get screeners or advance access to anything. They do get press kits sometimes (and much more often for movies than for TV shows.)

For movies out on DVD, if there's a disputed credit, usually someone will actually go pop in the disk and check. (The founder, Col Needham, has a staggeringly large collection of movies.) This makes it exceptionally accurate for that. Movie studios generally provide the information directly to the site for pre-releases, though rumors slip in from time to time. TV studios are less reliable about this - there isn't really a marketing push comparable.

For non-English films, user submissions are trusted much more heavily. Also more obscure films and actors. It works pretty well in practice.

This is only sort of related, but as someone who actually worked at IMDb for a time, thought it might be interesting. Most people assume IMDb is much more connected into the Hollywood machine than it really is. (I believe there's one IMDb employee who actually lives in the Los Angeles area. Most of the folks who actually manage cast lists are in England geographically.)

You realize now that you made this list that Darliton are going to find a way for Doug Flutie to appear on LOST. I'm thinking in a Jack flashback.
