A team of secret government operatives are infiltrating Major League Baseball this season. Their mission? Give away one million tickets to see their movie G-Force on its opening day. From Walt Disney Pictures and Jerry Bruckheimer Films comes G-Force, a 3- high-octane comedy adventure about a covert government program in which guinea pigs are trained to work in espionage. The film, opening nationwide July 24, teams up with MLB for the unprecedented G-Force Grand Slam Sweepstakes. If a grand slam is hit during the All-Star Game on July 14, the first million people who have entered on Disney.com will win a free ticket to see G-Force on its opening day.

The program marks the most comprehensive promotional sponsorship of Major League Baseball by a major motion picture ever and the first movie promoting its debut during the Major League Baseball All-Star Game since Disney's Angels in the Outfield in 1994.

"G-Force is a hilarious 3D comedy that family audiences will love," said Jim Gallagher, president of marketing for Walt Disney Studios Motion Pictures. "We hope one of the All Stars hits a grand slam, because what better way to launch the release than with a million enthusiastic sports fans showing up as part of opening day!"

Grand slams are on the rise with 18 grand slams having been hit so far this season, well ahead of the normal pace.

"By teaming the most significant sporting event of the summer with the most anticipated family movie of the summer, we hope to give fans a little something more to cheer for when they tune-in to the All-Star Game," said Tim Brosnan, Major League Baseball executive vice president, business. "Delivering tried and true forms of family entertainment, Disney and Major League Baseball are a perfect team."

"We think that G-Force hits a grand slam with comedy, adventure and innovative 3D, and we're excited to share the fun with audiences of all ages," said producer Jerry Bruckheimer.

The first million people who enter online at Disney.com between April 22 and midnight on July 14 will receive a code redeemable for one free ticket to the movie on its opening day (July 24) at participating theaters if a grand slam is hit during the All-Star Game, which will air live on Fox at 8 p.m ET. on July 14. Additionally, the more than 46,000 attendees of the All-Star Game, which takes place in St. Louis' Busch Stadium, will each receive a promotional card with a ticket code redeemable for a free ticket on opening day if a grand slam is hit.

The movie takes a front-row seat in the effort to select the starting lineups for this year's MLB All-Star teams. As the exclusive sponsor of in-stadium All-Star balloting, G-Force will appear on more than 20 million ballots distributed at the 30 MLB ballparks, at more than 100 Minor League ballparks, and through in-stadium messaging and announcements. Major League Baseball and Disney will select a child from local Boys & Girls Club of America chapters to participate in the in-stadium All-Star balloting launch ceremony.

Prior to the All-Star Game, 29 MLB Clubs will host "Walt Disney Pictures G-Force Days" including G-Force-themed trading card giveaways and movie ticket/prize-pack giveaways during the games.
