Fox Set For 'Alvin and the Chipmunks 2'

The chipmunks are tuning up for a bigscreen return in 2010.

Twentieth Century Fox will release sequel "Alvin and the Chipmunks II" on March 19, 2010. A followup had been expected, given the breakaway success of the first pic, which grossed $217.3 domestically and $141.1 million overseas for a worldwide haul of $358.4 million. But the film, which will be a co-production between Fox 2000 and New Regency, has no script yet. Furthermore, executives haven't settled on a concept for the sequel. The first film left off with the three singing chipmunks reuniting with their manager Dave Seville (Jason Lee).
