Get ready for the animated movie everyone will be talking about in 2015. The charming first trailer for DreamWorks’ “Home” is now online, and with it we meet the Boovs, an ever-optimistic, purple-tinted alien race who attempts to make Earth their new home in order to escape from a mortal enemy. Jim Parsons voices the Boov who’s front and center, with Steve Martin acting as their glorious leader. Rihanna plays Tip, a teenage girl who befriends the extraterrestrial cuties, and Jennifer Lopez is her mother, which is fitting because the celebrated 2007 children’s book on which it’s based, “The True Meaning of Smekday,” features a character named J.Lo. “Home” opens March 27, 2015, and boasts that concept album Rihanna is working on for the movie.
