A gang of hyperactive New Mexico high school kids faced down a sadistic serial murderer at the movies this weekend and came out on top in a big way.Disney's "High School Musical 3: Senior Year" -- the first installment of the 2-year-old franchise to graduate from cable TV -- recorded $42 million at the box office. The total gave it the best opening weekend ever for a movie musical, outpacing this summer's "Mamma Mia!" ($27.8 million) and last year's "Hairspray" ($27.5 million).
Lionsgate's " Saw V," the only place in America one can find more blood and gore than in the stock market, pulled in an estimated $30.5 million weekend gross. For the "Saw" franchise, that marks a record four sequels in a row to open at more than $30 million -- particularly noteworthy given that the movies have been scheduled very tightly, opening annually to tie into Halloween each year.
