'World War Z' Set to Become Brad Pitt's Biggest Opening Weekend Earner

After this weekend, Mr. and Mrs. Smith will no longer be Brad Pitt's biggest opening weekend earner.

The actor's World War Z is set to surpass the $50 million brought in by the 2005 spy film, which co-starred Angelina Jolie. Paramount expects the zombie apocalypse tentpole, which earned a B+ CinemaScore from audiences, to gross more than $60 million in its debut.

BOX OFFICE REPORT: 'Monsters University' Scares Up $30.5 Million on Friday 

WWZ earned $25 million Friday, placing the title at No. 2 on the domestic box office chart behind Disney/Pixar's Monsters University at $30.5 million.

The movie, co-financed with Skydance Productions, underwent an arduous production process that included numerous reshoots before finally making its way into theaters.

Pitt's last summer film was Quentin Tarantino's Inglourious Basterds, which opened to $38 million in August 2009. He also starred in Steven Soderbergh's 2007 heist sequel, Ocean's Thirteen, which opened to $36 million in June. And the actor opened the mythology epic, Troy, to $46 million in May 2004.
