This image was made by a deviantArt user named TimDrakeRobin. I agree with everyone on there( in case you didn't know who's on there, I put a list below) except Batman and maybe Wonder Woman. My picks are Henry Cavill for Batman and Jodi Lyn O'Keefe for Wonder Woman if I have to use Cobie Smulders for something else.
Here's who's in the picture:
Superman-Brandon Routh
Batman-Christian Bale
Wonder Woman-Cobie Smulders
Green Lantern-Ryan Reynolds
Flash-Neil Patrick Harris
Hawkgirl-Rose McGowan
Aquaman-Sam Worthington( I don't completely agree with this pick but can you think of anyone better?)
