Morena Baccarin, is awesome, and there are many times I would put her name forward, but, I don't think she is built right for Wonder Woman. In all the portrayals I can think of, Wonder Woman is a full figured, meaty girl (Not fat by any means, but, thicker). Morena is very skinny (Or at least was in V, SG-1 and Firefly)
Simon Baker is already 44, and doesn't look as Fresh Faced as that pic anymore. Should a first look at Flash be that old? A Trilogy, often takes 7 to 10 years, would Flash be OK to be 56+ year old actor in the third Movie?
