Transformers: Revenge of the Fallen is one massive movie. The Michael Bay-directed juggernaut earned an astounding $60.6 million on its opening day at the box office. No other film has earned that much money in the middle of the week, and only The Dark Knight ever banked so much in a single day (it grossed $67.2 million on opening day last summer).

How Transformers 2 will hold through the weekend will be very interesting to see. The fanboys sure came out in force on opening day. But Hollywood, hungry for a huge hit, will be closely watching whether they will return throughout the weekend. Check back later today for our full predictions in the Box Office Report.
