LOS ANGELES — “The Help” continues to clean up at the box office, taking over the No. 1 spot with $20.5 million in its second weekend.

The DreamWorks Pictures film starring Viola Davis, Emma Stone and Octavia Spencer in a drama about Southern black maids had debuted in second-place a week earlier. “The Help” raised its domestic total to $71.8 million and bumped 20th Century Fox’s “Rise of the Planet of the Apes,” which slipped to No. 2 with $16.3 million after two weekends at the top, according to studio estimates Sunday.

“Rise of the Planet of the Apes” remains a solid hit, lifting its domestic total to $133.8 million.
