i just had a scary thought. if Wright, speculatively, were to go with his original original plan...what if the end of this movie is Cassie Lang taking up the mantle? and, just to get it out of the way, i'd be just as disappointed in this as Pym fans. but i could see someone like Feige or Whedon seeing it as getting the best of both worlds; female for diversity + the Giant-Man powerset. Pym would be adventuring in the 60s (50s or whatever). Lang would be operating in the 80s. and Cassie (who is an adult hero in the Ultimates universe), who would be 6-9 during the action of the movie would be the one to pick up the torch in the present. it'd save them money on size-changing characters.
