IMDB says it was transfered from 24p to 35mm. I'm also curious what cameras they used in the film. Anybody have any guesses?

Well, here on IMDB:

it says they used a VX2000 and a PD150.

Thanks, Vito. I think I did not see that because I did not want to believe it. Thirty million from a budget of a 130k. Not bad. I wondered if it showed at sundance before it was blown up to 35mm.

Yeah, I remember when it came out that everyone was going nuts because it was shot on DV. Quite the sacriledge... A classic case of content making format irrelevant.

Was Open Water shot on minidv?Please search first before posting new topics on DV Info Net... I've merged your post into our gigantic four-year-old Open Water discussion thread.

I just put it on my netflix. I'm purposefully giving myself low expectations so I can enjoy it. I confess I'd never heard of this film until a few days ago when I took my son diving and a couple people on the boat were raving about it. Someone mentioned that in real life they found a camera (waterproof housed) inside a mako shark and that was part of the movie's inspiration. Not a good day at the beach if you ask me.
Regardless, I should have known Open Water would have already been dissected here and that my ignorance is not everyone else's ignorance. I apologize. I promise to search from now on . . . no matter how ignorant I am.

Just watched Open Water. If you like diving and/or the ocean and you haven't already seen it I can't imagine you wouldn't enjoy it. DVD extras on shooting Indies was inspiring too.
I did notice the inexpensive cams at first but then the movie took off and I was completely in the moment. I can't believe they stormed Hollywood with an ME66, a beachtek, a VX2000 and a PD150. Thumbs up to Lionsgate for buying and promoting this film.
