Paramount’s Transformers: Revenge of the Fallen continued to control the daily box office with ease on Monday. The Summer blockbuster grossed $14.85 million yesterday, which represented roughly one half of the combined box office take of all films for the day. Transformers 2 was down 54 percent from Sunday, which was nearly on par with the 55 percent daily slides both Transformers and Harry Potter 5 experienced on their respective first Mondays in July of 2007.

Transformers 2 has grossed $214.93 million in just six days of release. That ranks as the second largest six-day gross of all-time (behind only last year’s The Dark Knight). Through six days, Transformers: Revenge of the Fallen is running just 3 percent behind the pace of The Dark Knight, 38 percent ahead of Transformers and 43 percent ahead of Harry Potter 5.

The Proposal remained in second place with $2.76 million on Monday. The romantic comedy from Disney was down a solid 48 percent from Sunday, but was down 41 percent from last Monday. The 11-day gross for The Proposal stands at $71.92 million. When The Proposal crosses the $100 million mark in the near future, it will become the first Sandra Bullock film to do so since 2000’s Miss Congeniality, and the first Bullock film since 2003’s Two Weeks Notice to do so when adjusting for ticket price inflation.

Warner’s The Hangover continued to holdover well as the film grossed $2.58 million for the day. That represented a 50 percent fall from Sunday, and a slide of just 32 percent from last Monday. The Hangover has grossed an amazing $185.63 million in 25 days and looks set to see another solid performance over the upcoming holiday weekend.

After experiencing its largest weekend decline to date this past weekend, Disney’s UP rebounded nicely on Monday. The computer animated blockbuster from Pixar grossed $2.16 million yesterday, which was down 47 percent from Sunday and down only 23 percent from last Monday. However, UP could experience a notable drop on Wednesday when Fox’s Ice Age: Dawn of the Dinosaurs lands in theatres.

My Sister’s Keeper experienced the day’s best daily hold among wide releases. The drama from Warner Bros. starring Cameron Diaz and Abigail Breslin grossed $2.04 million on Monday, which was down just 40 percent from Sunday. After experiencing a large decline on Saturday, the film rebounded nicely on both Sunday and Monday. My Sister’s Keeper has grossed $14.48 million in four days, which is in line with pre-release expectations.
