According to an article in Los Angeles Times, Paramount and Nickelodeon are planning on a new Mighty Mouse movie in the not too distant future. The article cites the success 20th Century Fox has had with their two recent Alvin and the Chipmunks movies as the prime motivator for this project.
Mighty Mouse was a Terrytoons cartoon that ran for thirty years from the 1950s to the 1980s and was a major part of the old Saturday morning cartoon block for kids. The character was kind of a cross between Superman and Mickey Mouse and had one of the more iconic theme songs, thanks partially to comedian Andy Kaufman.
Whether or not this upcoming project will be fully animated or a mix of animation and live-action is still up in the air. At the moment Paramount and Nickelodeon are looking for a new writer and director.
If done right, this could be a really fun picture for kids and nostalgic adults. The new film will deal with the classic cartoon hero in a modern world.
