Ant-Man is jumping the gun if it includes both Hank Pym and Scott Lang as the character. It should deal solely with introducing the audience to Hank Pym and Janet Van Dyne (as Wasp), with Ultron as the main villain. A potential Ant-Man 2 should introduce Scott Lang and perhaps have the Vision as its villain.

Then again, I'm not entirely sure Ant-Man can work as its own movie. If anything, I think the plot of Iron Man 3 should have revolved around Hank Pym et al instead of whatever it's doing. "Ant-Man" isn't exactly a name people unfamiliar with comics can get excited about.

That being said: Nathan Fillion as Hank Pym, Rachel McAdams as Janet Van Dyne, Ryan Gosling as Scott Lang (I dare you to make a The Notebook joke), and either Brent Spiner or Jeff Bennett for Ultron.
