Will Smith's con-man caper "Focus" dethroned "Fifty Shades of Grey" at the box office, but the film's modest $19.1 million opening still left questions about the drawing power of the once unstoppable star.

Warner Bros.' "Focus" easily topped all competitors on a weekend with little competition at North American multiplexes. The weekend's only other new wide release, Relativity's horror film "The Lazarus Effect," opened in fifth place with $10.6 million.

But the weekend was largely seen, fairly or not, as a referendum on Smith's star power. "Focus," written and directed by the "Crazy, Stupid, Love" duo Glenn Ficarra and John Requa, is Smith's first film since 2013's "After Earth," a sci-fi flop in which co-starred his son, Jaden.

Estimated weekend ticket sales:

1. "Focus," $19.1 million.

2. "Kingsman: The Secret Service," $11.8 million.

3. "The SpongeBob Movie: Sponge Out of Water," $11.2 million.

4. "Fifty Shades of Grey," $10.9 million.

5. "The Lazarus Effect," $10.6 million.

6. "McFarland, USA," $7.8 million.

7. "American Sniper," $7.7 million.

8. "The DUFF," $7.2 million.

9. "Still Alice," $2.7 million.

10. "Hot Tub Time Machine 2," $2.4 million.
