Box Office: 'Tomorrowland' May Nab $45M Over Holiday Weekend

The Memorial Day weekend's other major new offering, the 'Poltergeist' remake, could hit $30 million.

Disney's Tomorrowland may nab $45 million during the four-day holiday weekend, while Universal's holdover Pitch Perfect 2 may gross $42 million in its second weekend. 

Meanwhile, there's also a race brewing between Warner Bros. and Village Roadshow's Mad Max: Fury Road and MGM and Fox 2000's Poltergeist. George Miller's actioner and Gil Kenan's horror film are both aiming for $30 million over the holiday weekend. 

Tomorrowland, directed by Brad Bird, had a limited release in only 701 theaters beginning at 7 p.m. Thursday night. The film, which is expected to top the U.S. box office, will expand wide to 3,972 theaters for the Memorial Day weekend.

George Clooney stars as an inventor who takes along a spirited teen (Britt Robertson) to an alternate world called Tomorrowland. The $180 million movie, an ode to Walt Disney's hopes for creating a utopian society, also stars Hugh Laurie. Bird co-wrote the script with Damon Lindelof.

Poltergeist, the other new offering over Memorial Day weekend, scared up a nice $1.4 million from approximately 2,500 locations after opening at 8 p.m. Thursday night.

Directed by Gil Kenan and produced by Sam Raimi, Poltergeist is a remake of the 1982 cult classic and stars Sam Rockwell, Rosemarie DeWitt, Jared Harris and Jane Adams.
