I suggest Waterworld.

I know the movie kind of makes fun of itself buy you guys could make it watchable.

I agree that this would be an awesome Riff.  Dennis Hopper's scenery chewing would bring cause a whole lot of Ham Alerts.

However, as Costner movies go, the best for Riffing would be "Robin Hood: Prince of Thieves."  All things considered, I think it's a shame that MKB haven't tackled a Costner movie.  He has so many movies that are deserving of the treatment.  Even "Dances with Wolves" and "The Postman"  (Hell, especially "The Postman") deserve the full Rifftrax skewering.

Waterworld would be great.  But the one Costner film I really want to see riffed is The Untouchables.  I like the film a lot, but the cheesiness of Kevin Costner *and* Sean Connery *and* Robert DeNiro would be enough to propel the film into riff heaven.

I would watched WATERWORLD with a Rifftrax commentary.
