‘Semi-Pro’ scores at box office

? Will Ferrell’s basketball comedy “Semi-Pro” dribbled to the top of the weekend box office, but it fell short of his previous blockbuster openings in the sports spoof genre, according to studio estimates Sunday.

The New Line Cinema film, starring Ferrell as the owner of a fictional basketball franchise, grossed $15.3 million in its weekend debut. That was lackluster compared to Ferrell’s 2006 NASCAR parody “Talledega Nights: The Ballad of Ricky Bobby,” which opened at $47 million, and last year’s figure skating comedy “Blades of Glory,” which earned $33 million in its first weekend.

Box office analysts said “Semi-Pro” likely suffered because it was released during a normally slow season and was rated R, while “Talledega Nights” and “Blades of Glory” were rated PG-13.

Estimated ticket sales for Friday through Sunday at U.S. and Canadian theaters, according to Media By Numbers LLC. Final figures will be released today.

1. “Semi-Pro,” $15.3 million.

2. “Vantage Point,” $13 million.

3. “Spiderwick Chronicles,” $8.8 million.

4. “The Other Boleyn Girl,” $8.3 million

5. “Jumper,” $7.6 million.

6. “Step Up 2 The Streets,” $5.7 million.

7. “Fool’s Gold,” $4.7 million.

8. “Penelope,” $4 million.

9. “No Country For Old Men,” $4 million.

10. “Juno,” $3.4 million.
