If you're still not convinced you want to pay $20 a ticket to see Pacific Rim in 3D IMAX this weekend, the Warner Bros. and Legendary Pictures sci-fi thriller is now offering you a chance to watch the opening and closing credit sequences online. Created by Imaginary Forces, these scenes give no real plot points away, except that you'll be paying to watch a lot of Mechs smash a lot of Monsters in this Guillermo del Toro directed blockbuster. Check these out before finally committing to that Grown Ups 2 ticket. You might change your mind about how you spend your Saturday night. And then again, you might not!
