Despite massive hype, 3-D surcharges, and an actual good movie, it seems audiences were a bit gun-shy about running out to see Transformers: Dark of the Moon on opening day. The Wednesday grosses for the threequel tallied $37.2 million (plus an additional $5.5 million from Tuesday night), down dramatically from the $62 million Revenge of the Fallen earned on its opening Wednesday in 2009. Not that Paramount is too disappointed; the studio is expecting Dark of the Moon to have the highest worldwide gross in the franchise before it explodes out of theaters later this summer. Still, shouldn't this have opened bigger? [Deadline]
