My box office gurus are telling me this past weekend’s gory blockbuster 300 still has lots of momentum for this coming Friday + Saturday + Sunday. The cheapo Warner’s epic should march to 1st place for another big $37 mil, followed by Sony’s Sandra Bullock thriller Premonition with $18 mil. (Nice counter-programming.) For the weekend of March 23rd, another Warner’s pic, Teenage Mutant Ninja Turtles (TMNT) is sure to debut #1 because of the obvious nostalgia factor, with Paramount’s engaging assassin thriller Shooter starring Mark Walhberg (fresh off his Oscar nod) in 2nd place and 300 dropping to 3rd.
