When Interstellar and Big Hero 6 open this weekend, they’re both expected to debut well past $50 million, according to Hollywood Reporter.

Tracking services estimate both films raking in anywhere between $50 to $60 million at the box office.

Written and directed by Christopher Nolan, Interstellar is the story of a team of astronauts striving to save the human race. The film stars Matthew McConaughey, Anne Hathaway, Jessica Chastain and Michael Caine. At 169 minutes, Interstellar is Nolan’s longest film to date.

Big Hero 6 chronicles the special bond that develops between Baymax, a plus sized inflatable robot and kid genius Hiro Hamada. Hamada transforms Baymax and his pals into an unlikely team of high-tech heroes who aid and protect the city of San Fransokyo from a mysterious supervillain. The animated acton-comedy adventure is based on the Marvel Comics manga of the same name.

The Disney CGI film features the voices of Jamie Chung, Maya Rudolph, James Cromwell, Damon Wayans Jr., and Alan Tudyk.

If Interstellar and Big Hero 6 both open to $50 million+ this weekend, it’ll only be the fourth time in history. In the previous instances, they were also a pairing of a live action and animated movie: Monsters University and World War Z; Madagascar: Escape 2 Africa and Prometheus; and Wall-e and Wanted. And in all three cases, the animated film took the top spot.
