The latest TV spot for The Smurfs 2 promises twice the trouble, adventure, and fun than we saw in 2011's The Smurfs. Gargamel (Hank Azaria) is back with some new evil helpers known as The Naughties (Christina Ricci and J.B. Smoove), who kidnap Smurfette (Katy Perry) and bring out her evil side. Watch as Smurfette takes the famous U.K. landmark The Eye of London for a spin in the latest footage from director Raja Gosnell's sequel, in theaters July 31.
