With a feat the original Transformers film of 2007 could not accomplish domestically, the sequel earned in 76 days a whopping $400 million domestically.
Michael Bay believed with the lack of heavy promotion by the studio, the film would not earn nearly as much as perceived..."I have been waiting, and waiting for the anticipation of an 'event movie' to make it into the 'public zeitgeist.’ You all talk so glowingly about Transformers being the movie of the summer but unfortunately this has not gotten out to the public. I still run into so many people even this weekend with kids that ask 'is that movie coming out this year?"
Many may downplay the overall appeal, script, acting, special effects, true to source material or simply the direction Bay decided to take the film but apparently that didn't stop the masses from flocking to the theater during the film's run.
We already know a sequel is in the not too distant future and BoxOfficeMojo has a tentative date of 7/1/2011. I doubt that will be the actual date, but who knows with Hollywood today?
