Before breaking out into North American television and film, Joel Kinnaman was shortlisted for the lead role in Thor for a very good reason. Marvel Studios doesn't always test actors in the role they're actually considering them for (see: Tom Hiddleston) and that's what makes rumors about the Swedish actor up for a Marvel role interesting.
After starring in The Killing and earning memorable roles in Safe House and The Darkest Hour, Kinnaman nabbed the coveted lead role as the next RoboCop, set to establish him as a household name. Both RoboCop and Edgar Wright's The World's End begin filming this September, and after that it's conceivable that they could work together for Ant-Man.
