Box office top 20: Will Smith's 'Focus' on top with $18.7M

New York: Will Smith's crime caper 'Focus' debuted with $18.7 million, according to final figures Monday, while the previous North American box office leader, 'Fifty Shades of Grey' sunk to fourth place.

The somewhat weak debut of Warner Bros.' R-rated 'Focus' co-starring Margot Robbie, handed Smith another no. 1 box office opening but came in slightly below expectations. Winter weather across much of the Midwest and the South contributed to the film's modest performance, which is Smith's first movie since his 2013 flop, "After Earth."
