This coming Saturday at 10pm ET/PT, Showcase presents the network premiere of 13 Going on 30, starring Jennifer Garner and Mark Ruffalo. On September 22nd, our friends at Alliance Films will release Ghosts of Girlfriends Past on DVD and Bluray, which also stars Jennifer Garner as the romantic lead alongside Matthew McConaughey -- alright alright alright!

Plus, since it's an Alliance Films joint, you know it'll have the classic Canadian front-and-back English/French combo slipcover:

In celebration of this fortuitous coincidence, we're giving away DVD copies of Ghosts (er, Hanté) to the first few people who can spot the four differences in the following two images. 

Think you've got 'em all? E-mail us at webmaster@showcase.ca with your findings, and be sure to put "JENNIFER GARNER GIVEAWAY" in the subject header. We'll get back to you if you've won, but don't sweat it if you miss out -- there will be new giveaways each week. (Click here for full rules and regulations.)
