Friday saw a 25.7% decrease in box office revenue over the previous Friday.

Returning to theatres in number one spot for Friday is Sacha Baron Cohen with his new shockumentary BRUNO, which managed an estimated $14.1M on Friday. This is up on his previous opening Friday effort BORAT, leaving BRUNO to be another big winner for the comedian although its subject matter may weaken its legs and overall box office.

Second spot goes to ICE AGE: DAWN OF THE DINOSAURS, which held well with an estimated $8.6M on Friday. The film lost around 50% of its audience on last Friday which is a good hold given the competition and its less than great word of mouth. Against a $90M budget the film has now crossed the $100M mark domestically.

TRANSFORMERS: REVENGE OF THE FALLEN enters third spot for Friday, earning an estimated $7.6M. The gloss is coming off this mega-blockbuster rapidly, losing 58% of its audience on last Friday. However, the film has earned a huge $322M since opening domestically and a further $333M at the foreign box office, making this $200M investment a huge winner.

Michael Mann's PUBLIC ENEMIES enters fourth spot with an estimated $4.3M for Friday, down 57% on last Friday. Although suffering a similar drop to Transformers, PUBLIC ENEMIES did not have as far to fall and despite its $100M budget, the film is chugging along nicely with $66M in the bank as it enters its second week of release.

The only other opener in the Top 10 for Friday is the Fox rom-com I LOVE YOU BETH COOPER which sputtered out of the gate with a very small estimate of $2M. Despite starring young teen sensation Hayden Panettiere, the film is a virtual non-starter and will disappear quickly.

The remaining box office estimates for films on Friday are as follows: THE PROPOSAL ($3.4M), THE HANGOVER ($3M), UP ($1.45M), MY SISTER'S KEEPER ($1.43M), and NIGHT AT THE MUSEUM: BATTLE OF THE SMITHSONIAN ($0.49M).

The North American box office took in an estimated total of $46.7 million for the whole of Friday 10th July 2009.
