Who should play Supergirl?

My choice:

Nicola Peltz, the girl from transformers

Nikki Glaser?

@blade_r: Never heard of her but based purely on looks she's past playing girls and fully in woman territory.

Imogen Poots.

Lol yeah I was going to say in my first post that she might be a little too old to play a girl.

Personally I think her older sister Dakota would be a better choice. She could still pass for 16, and she usually plays either a "smarter-than-everyone-older-than-her-in-the-room" girl, or a "troubled loner" type. Depending on the era, both fit Kara very well.
