Today saw a couple developments in regards to the Edgar Wright Ant-Man Movie.
With the announcement that Michael Douglas is playing Hank Pym came confirmation that Paul Rudd is Scott Lang.
Then Wright posted an interesting Tweet referencing an interview from 2006 in which Wright basically gave the synopsis for Ant-Man.
His response in the interview offered there will be a prologue set in the 1960s where Hank Pym will be seen in action as Ant-Man.
Cinema Blend points out the obivious, which is there will be another younger actor playing Hank Pym and Ant-Man for the 1960s scene (assuming it's still in the script).
Ant-Man hits July 31, 2015.
