3. Hank Pym's Ant-Man
A first look at Hank Pym would be pretty cool, given that his Ant-Man movie is due for release as part of the MCU's Phase 3 at the end of 2015, from director Edgar Wright. An appearance after the credits in Iron Man 3 would be a refreshing way to do the 'big reveal' regarding which actor is set to play Pym in his own movie. In June of last year, it was hinted that the scene may
already have been confirmed, with Pym making an on-screen appearance with Radioactive Man. Another plausible idea, however, could be a dual cameo with Agent Coulson, revealing that Pym was the man who built the LMD which was used to bring the Avengers together by having them believe that Loki had killed the real Phil Coulson. Either way, we'd love to see Hank Pym on the big screen for this first time.
