Despite CHLOE's official site only states that the film will open in NY and LA on 3/26/2010, Music Box Theatre at Chicago confirms that they will also open CHLOE on 3/26/2010.

Maybe Sony Pictures Classics will open CHLOE in Chicago that soon because they want to get Roger Ebert's positive review as soon as possible?
Or does it means that CHLOE will opens wider than expected?
