Former LOST star Evangeline Lilly could soon be blowing up in the size-changing world of Marvel's Ant-Man movie. According to Variety, The Hobbit: Desolation of Smaug star could follow Paul Rudd, Michael Douglas and Michel Pena as an official cast member, although her specific role hasn't been announced. The "insider" word is that Lilly's character could be Pym's daughter and Lang's love interest. If true, that could mean a dramatic reworking of Janet Van Dyne's character -- a founding member of The Avengers who has until now been left out of the Marvel movie universe. Of course, it could be an original character and Janet could remain left out of Ant-Man's movie lore.
