Even in this age of superhero cinematic universes, it's fair to say that none of us expected Sharkboy and Lavagirl to return to our screens but, what do you know, that's what's happening this New Year's Days. Robert Rodriguez directed family movie The Adventures of Sharkboy and Lava Girl in 3-D back in 2005 and on January 1st - more than 15 years later - it'll be getting a sequel/spinoff.
