After its $60.6 million debut on Wednesday, Paramount's Transformers Revenge of the Fallen fell to $27 million on Thursday -- not nearly so impressive as the Wednesday result but impressive for a Thursday nonetheless. With $67.2 million already accumulated, box-office analysts are predicting that it could wind up with one of the heftiest five-day grosses ever. The movie is packing them overseas as well. Daily Variety reported on its website Thursday that the Michael Bay movie earned a whopping $59 million on Wednesday. "This is the best opening number I can ever remember," Andrew Cripps, Paramount's head of international distribution, told Variety. It's expected to dwarf the competition at the box office this weekend as it tries to unseat The Dark Knight, the current record holder with $203.8 million over five days. Its principal competition this weekend will come from two romantic comedies, the holdover The Proposal from Disney and the Warner Bros./New Line drama My Sister's Keeper , starring Abigail Breslin and Cameron Diaz. Also opening in limited release -- but in most of the major markets -- will be the Stephen Frears costume drama Cheri , starring Michelle Pfeiffer.
