All things, as they say, must come to an end. Some, like, uh, The Love Guru, fade out fast (oof, that loss to Get Smart musta hurt). Others, like EW.com’s Summer Box Office Challenge stick around for months. But following last week’s win by “patbo236,” we’ve arrived at a turning point in our little game — the first 10-week series of our summer contest has concluded (congrats to the overall winner, “Scrape”), and a new 10-week installment is starting up. Think you’ve got what it takes to win our weekly competition…and take home some free DVDs along the way? Think you can do it this coming weekend, when Wall-E will battle Wanted for box office supremacy? Just click over to the game and register your picks by Friday at 8 p.m. Eastern time.
