Warner Bros. and Fox Interactive have found success in a partnership between MySpace and the upcoming epic film 300, writes AdWeek.

For the last couple of months, Warner Bros. has maintained a MySpace page for the film, a common tactic for the movies in the last year or so. But in this case the promotion was exposed to the entire MySpace user population.

That's because the movie sponsored a feature upgrade on the site that alerted users that they could now store 300 photos on their profile thanks to the movie 300. That message has been shown to all users uploading photos since January 2.

Overall, the promotion resulted in billions of ad impressions, eight million viewings of the trailer - which autoplays on the 300 page - and over 213,000 "friends" for the movie's profile page. Some MySpace members were also able to attend a pre-release screening of the movie.
