It seems that fans shouldn't expect a sequel to one of this year's big animated 3D hits. According to, DreamWorks Animation has announced that there won't be a sequel to this year's animated hit Monsters Vs. Aliens.

While the film performed well domestically, taking in $198 million, a sequel to the film was never a sure thing due to a lukewarm international reception. The film made $380 million worldwide, but performed poorly in several key international markets.

"I'd like to tell you there's a perfectly rational, clear and easy answer as to why not, but there isn't," said DreamWorks Animation head Jeffrey Katzenberg.
