What next? Well, there's post production of course, but starting work on the third movie might not be the worst idea (for us fans at least). Joss Whedon's Avengers: Age of Ultron stars Chris Evans, Chris Hemsworth, Robert Downey Jr., Mark Ruffalo, Jeremy Renner, Scarlett Johansson, Aaron Taylor-Johnson, Elizabeth Olsen, Cobie Smulders, Don Cheadle, Paul Bettany, James Spader, and Samuel L. Jackson, and is set to be released on May 1st, 2015.
