I think Zack Snyder did a pretty good job of casting Batman and Superman. But honestly, as much as she's stolen America's heart, Gal Gadot wouldn't be my choice for Wonder Woman. I would've gone with Caitriona Balfe from Outlander.

As for Barry Allen, I hardly think the film could've been more off the mark. Strangely enough, I feel the best choice for the role is actually Rick Cosnett, who was on the Flash TV show as Eddie Thawne. I think that guy just IS Barry Allen from the comics!

For Aquaman, I think the person who most resembles the comic is Alexander Skarsgaard, by far.

Honestly, some of these drive me crazy because I wish so much I knew how to photoshop. I'd be all over them!
How about anyone else?
