Disney’s Tomorrowland topped the box office over Memorial Day Weekend, but did so in the lowest holiday box office since 2001.

The film pulled in just $41.7 million in its first four days after theaters — a disappointing debut for a film that cost $180 million to produce.

Disney, however, feels like it’s too early to judge the film’s performance for two reasons. One, it’s the only PG-rated family film in theaters until Disney and Pixar’s Inside Out opens on June 19. And two, many schools have yet to close for the summer.

“It’s not ever ideal to be below your estimate before the weekend starts, but it feels like it’s too early to judge the run,” Disney’s Distribution EVP Dave Hollis told the AP. “We are optimistic that originality and the vision that Brad Bird put on the screen is something that people will find and evangelize and hopefully get other folks to show up.”

Last weekend’s top film, Pitch Perfect 2 and Mad Max: Fury Road took in $30.8 million and $24.8 million, respectively, for the #2 and #3 spots, while Avengers: Age of Ultron lands at #4 with $21.6 million.

The weekend’s other wide release, the Poltergeist remake opened in fifth with $26.5 million.

That’s a wrap for this weekend. This upcoming week, look out for the release of The Rock’s apocalyptic action film, San Andreas.

This weekend’s top 10 is as follows:

1. “Tomorrowland,” $41.7 million.
2. “Pitch Perfect 2,” $38.5 million.
3. “Mad Max: Fury Road,”$32.1 million.
