"Oblivion" cruised to the top of the weekend box office.

The Tom Cruise science-fiction thriller led Hollywood with a $37 million debut.

Though many people Friday were caught up in coverage of the manhunt for the suspects in the Boston Marathon explosions, it seems to have had little effect on how the film fared.
