Citing off-the-charts tracking and advance sales, Steve Mason at Fantasy Moguls is predicting a $64.3 million opening weekend for “Twilight.” Disney’s animated “Bolt,” which sneaked last Saturday to try to spread word of mouth, will come in at No. 2 with $40.2 million, Mase thinks. He’s also predicting strong holdover business for “Quantum of Solace” ($29.77M) and “Madagascar: Back 2 Africa” ($18.6M).
