Watch M. Night Shyamalan's daughter slay the national anthem

M. Night Shyamalan must be a proud pop.

Last night, the director's daughter, Saleka, performed the national anthem before the Philadelphia 76ers game -- and she nailed it.

But that’s not the only reason for him to smile. His psychological thriller Split exceeded box-office expectations over the weekend with an estimated $40.2 million in ticket sales. The film, which was made for less than $10 million, stars James McAvoy as a man with multiple personalities.
