Why would anyone do that?!
Family Edited DVDS, Inc. is a company that takes movies with objectionable content and edits it out in order to create a "family friendly" experience - and the studios are pissed!
Paramount, Warner Bros., MGM, Disney, Universal and Fox filed a lawsuit against the company and its leader, John Webster, for editing movies such as Iron Man 2, The Hurt Locker, Prince of Persia and Date Night, then selling them for profit.
The studios claim that the reproduction of the films violates their exclusive copyrights. Not to mention that selling its films in DVD-R format makes them "highly vulnerable to further unauthorized copying and other forms of infringement."
Family Edited DVDs are currently advertising a "liquidation" sale, so we'll assume they are running scared. The studios are requesting permanent injunctive relief.
So much easier just to watch PG movies! Lame.
