ANT-MAN vs. Yellowjacket:

There will be two big fights between the hero and villain in ANT-MAN; one that takes place in a briefcase as it falls out of a helicopter where they're literally fighting around objects in the case; Lifesavers, keys, an iPhone, etc. and using said objects against one another. The final battle between both characters takes place in Scott Lang's daughters' room on the Thomas the Train set (as seen in the recent trailer). As the battle rages on, we'll see both characters enlarge certain objects while they're still shrunk, accidentally making a giant ant and, eventually, Thomas the Train, which crashes out of the bedroom, crushing a car on the street. Crazy stuff and obviously making full use of the shrinking and enlarging that goes hand-in-hand with ANT-MAN's powers.

On The Wasp:

Evangeline Lilly is playing Hope Van Dyne in the film, as we know, and our source indicates that she will indeed become The Wasp, but you will NOT see it happen in ANT-MAN.
