If you, like many, were caught unaware that you could have been watching an IMAX print of Raiders Of The Lost Ark instead of watching Bradley Cooper pretend to be a writer (or, more likely, doing anything else), you're in luck. Due to popular demand and the fact that it made some money but not nearly enough money, Raiders has extended its "limited" run beginning today in more than 300 theaters across the U.S. and Canada. Check your local listings to find out if you live in the U.S. or Canada.
