It was a battle between two Dreamgirls stars at the box office this weekend.

After back-to-back roles in music-related dramas, Beyonce Knowles proved she could deliver without having to sing a note. Obsessed, a thriller produced for approximately $20 million, pulled in nearly $29 million for a 1st place finish. The film, also featuring two NBC stars (The Office’s Idris Elba and Heroes’ Ali Larter), more than doubled last week’s champ, 17 Again.

Meanwhile, an Academy Award winner and an Iron Man joined forces for a surprising fourth place finish. The Soloist, costarring Jamie Foxx and Robert Downey Jr., didn’t even cross the $10 million mark. Although it was once considered as a pre-Oscars release, the film’s debut grossed less than last week’s nominee-filled entry, State of Play.
