Deadline: The momentum just keeps building. Saturday has played out well so far for this weekend’s big opener, Paramount’s Transformers: Age of Extinction and it is holding on very strongly going into evening and late night showings. The thinking now is that the Michael Bay-directed franchise could gross anywhere between $103M to $105M for the three-day which would put it right between the grosses of the last two Transformer installments’ Friday to Sunday grosses. But that would not be an apples-to-apples comparison as they both opened on Wednesdays and had two more days of play. What a great win for the filmmakers, the studio and its top-notch marketing and distribution teams opened this lengthy, 2:45-minute film. More later as late night numbers roll in.
