It's now officially a rock-'em, sock-'em summer! Paramount's Transformers 2: Revenge Of The Fallen shattered the Wednesday opening record set by Harry Potter And The Order Of The Phoenix (#5) in 2007 - $60.6M vs $44.2M. Even better for the studio, Transformers 2 came in 2nd only to 2008 box office phenomenon The Dark Knight for biggest opening day ever: $60.6M vs $67.1M. So now 2007 Spider-Man 3's $59.8M single day take drops down to #3. The robot sequel grosses from 4,234 North American theaters are $16M more than Paramount expected. That puts the sci-fi actioner on track for a $175M five-day opening despite overwhelmingly lousy reviews. But Paramount boasted how exit polling showed that 91% of the audience said "they liked this movie as much or better than the first". So this Decepticons vs Autobots battle is reviewer-proof.
