Nathan Fillion & Eva Longoria To Join Cast Of The Avengers? The rumor that Nathan Fillion and Eva Longoria have joined the cast of Joss Whedon’s The Avengers continues to pick up steam. Should the rumors be true, Fillion, a long time Whedon collaborator, would portray Dr. Henry Pym , aka Ant Man , and Longoria would play his wife, Janet Van Dyne , aka The Wasp . Supposedly the two of them would show up as S.H.I.E.L.D. scientists before revealing their true, super powered nature. Please Leave A Comment- Source- comicbookmovie
