I guess if Phineas and Ferb can team up with Star Wars, this isn't quite as far fetched as it may seem. Still, I could think of several other team up movies I'd rather see. I suppose it will be OK, especially if they handle the Quest team properly. Jonny's voice seems off, but I'm so used to the originals that I may never think of anyone else doing it.
It also seems like they are taking all the best parts of the great Quest episodes, the Robot Spy, Jezebel Jade, the jet packs and who knows what else and cramming them into one movie. Not much originality going on there, huh?
