Obsessed (2009)
Beyoncé protecting her husband, Idris Elba, from psycho seductress Ali Larter? The instant we heard the plot of this thriller, we were obsessed. And we weren’t the only ones. The campy drama, made for a relatively teeny $20 million, opened at No. 1 (with more than three times the gross of The Soloist, which came out on the same day) and earned close to $80 million overall.
