Disney's "Big Hero 6" earned an estimated $15.6 million on Friday, behind first-place "Interstellar's" $17 million debut. But the animated all-ages superhero movie, based on a Marvel comic, is expected to pull ahead of the Matthew McConaughey space epic Saturday, and win the weekend, according to The Hollywood Reporter.

"Big Hero 6" is trending to earn between $56-58 million domestically, according to THR, while Christopher Nolan's cosmic follow-up to "The Dark Knight Rises" is estimated to finish in second place with $53 million.

If the estimates hold, this will be the fourth time that two films opening on the same weekend have earned over $50 million. THR also notes that in each instance it was an animated film opening against a live-action film, and in each match-up, the animated film won the weekend. The last match-up was 2013's "Monsters University" opening opposite "World War Z."
