LOS ANGELES — “The Dark Knight Rises” was on track to earn $160 million, which would be a record for 2-D films, over the weekend following a mass shooting at a Colorado screening of the Batman film.

Citing box office insiders, The Hollywood Reporter, Los Angeles Times, New York Times and other media outlets reported Sunday that the latest Batman sequel earned $160 million to $162 million.

That amount would best the $158.4 million debut of “The Dark Knight” in 2008 and give “Dark Knight Rises” the third-highest domestic weekend opening ever, after the 3-D films “The Avengers” with $207.4 million and “Harry Potter and the Deathly Hallows — Part 2” with $169.2 million.

Tickets for 3-D films cost more than 2-D screenings, netting extra cash at the box office. Movies released in 3-D typically earn under half of their income in 3-D screenings, sometimes as little as a third.

Sony, Fox, Disney, Paramount, Universal and Lionsgate joined “Dark Knight Rises” distributor Warner Bros in publicly withholding their usual revenue reports out of respect for the victims of the deadly shooting early Friday and their families.

Box-office tracking service Rentrak also did not report figures following the Aurora, Colo., shootings that killed 12 and injured 58 at a midnight screening of the Batman sequel on Friday.
