Transformers: Revenge of the Fallen continued its tremendous start over the weekend. The sci-fi action film from Paramount and DreamWorks grossed $108.97 million over the weekend and $200.08 million in its first five days of release. The five-day start for Transformers 2 was the second largest of all-time, behind only the $203.77 million five-day start of The Dark Knight last July. The film’s opening weekend was easily the largest opening weekend of 2009 thus far and ranked as the seventh largest of all-time (it ranked as 15th largest of all-time when adjusted for ticket price inflation).

Although pre-release expectations for the film were enormous, Transformers 2 was able to surpass those expectations over the last few days. Through five days, Transformers 2 is running a whopping 50 percent ahead of the pace of the previous Transformers film and 43 percent ahead of Harry Potter & the Order of the Phoenix, both of which opened in July of 2007. Also of note is the fact that grosses for Wednesday and Thursday made up an extremely high 46 percent of the film’s five-day total. That stat and the immense size of the film’s five-day start, suggest that Transformers: Revenge of the Fallen will be significantly more front-loaded than the previous Transformers film.

Disney’s The Proposal fell to second place with $18.58 million. The romantic comedy starring Sandra Bullock and Ryan Reynolds was down 45 percent from last weekend. The film took a slightly larger than expected hit from new competition from Transformers 2 and Warner’s My Sister’s Keeper, but has still grossed a very solid $69.16 million in ten days of release. The Proposal is currently running 10 percent ahead of 2006’s The Devil Wears Prada. Look for the film to hold up well this week in the days leading up to the Fourth of July holiday.

After slowing some during the midweek, The Hangover rebounded nicely over the weekend. The comedy blockbuster from Warner Bros. grossed $17.02 million, which was down just 36 percent from last weekend. The film’s hold was one of the best among wide releases this weekend and was impressive given the presence of Transformers 2 in the marketplace. The Hangover has grossed $183.05 million in 24 days and will zoom past the $200 million mark next weekend.

Disney’s UP finished in fourth with $13.06 million. The acclaimed computer animated film was down 44 percent this weekend, which was by far the film’s biggest weekend percentage decline to date. UP was hurt this weekend by both Transformers 2 and from last weekend’s gross being inflated by terrific business on Father’s Day. UP has grossed $250.23 million in 31 days, making it the highest grossing film of 2009 to date domestically. However, UP will only be able to make that claim for a few days before it is passed up by Transformers 2.

My Sister’s Keeper opened in fifth place with $12.44 million. The drama starring Cameron Diaz and Abigail Breslin debuted in line with pre-release expectations. My Sister’s Keeper opened 8 percent below 2004’s The Notebook, which was also directed by Nick Cassavetes. However, that gap jumps to 20 percent when adjusting for ticket price inflation. My Sister’s Keeper opened with $5.10 million on Friday, but slowed down quite a bit as the weekend went on.

Sony’s Year One self-destructed in its second weekend of release. The Harold Ramis directed comedy starring Jack Black and Michael Cera slipped to sixth place after experiencing a 69 percent slide from last weekend. Year One has grossed $32.53 million in ten days and is on pace to finish its run with a very disappointing gross in the area of $40 million to $45 million.

Although it was playing in just 495 locations, Away We Go was able to claim tenth place. The Sam Mendes directed film from Focus grossed $1.71 million for the weekend, which brings the film’s 24-day total to $4.09 million.

This weekend’s combined box office of just over $200 million was up 7 percent over the same weekend last year and up a healthy 33 percent over last weekend.
