These are not spoilers for the Antman movie because I have not seen it yet. Some suggestions for Antman (you could put them in the DVD deleted scenes or in the movie if you really like them):
Have a villian say to Antman, "I am going to step on you like the ant you are."
How about Antman gets captured by a boy or girl and placed in an ant farm. Of course Antman escapes.
Where is Antwoman?
I guess I should go see the movie to find out if any of the above ideas are part of the movie.
