You never know what's going to be popular at Sundance. There's a surprise around every corner. Case in point: today's press screening of Sleep Dealer. It's a Mexican film with no big names, but it does have a cool concept. It's set in the near future, where people can have nodes implanted in their bodies and use those to connect to a vast super-Internet. You can even upload your memories to the system and sell or broadcast them.

I hadn't heard anything about the movie one way or the other. Like I said, apart from the nifty premise, there's nothing distinctive about it. It was screening at the same time as Barry Levinson's What Just Happened?, which has a huge all-star cast. And yet the Sleep Dealer showing was packed. People were lined up early. Some people had to be turned away. For some reason, everyone had chosen this film.

The funny part? At least 20 people wound up walking out on it. General consensus is that it had neat ideas but poor execution, and that it was boring. (That's more or less how I felt about it.) It just goes to show, you never know what's going to be popular. The process of discovering is part of the fun.
