Everybody knew that The Chronicles of Narnia: Prince Caspian was going to win the box office last weekend, right? And it did indeed come in at No. 1 (even with a disappointingly low $55 million), right? You know, sheesh — this box office prognostication thing is easy! Anybody can play!

And, hey, with our Summer Box Office Challenge, anybody can. (To wit, 80 percent of last round’s players correctly saw Prince Caspian ruling the multiplex during its opening weekend. Smart, people, smart!) Now entering its second month,’s game allows folks at home to take a stab at foreseeing each weekend’s final box office rankings, with a set of DVDs going to the person whose crystal ball is the clearest. Think you’ve got what it takes? Think Indiana Jones and the Kingdom of the Crystal Skull is going to triumph this weekend? (And, well, if you don’t, maybe this game isn’t for you.) Just click on over to the game before Friday at 8 p.m. Eastern Time and give it a crack. (Get it? Indiana Jones…whip…crack…? Eh, just have fun!)
