I picked Urban because he is a great actor and displays a look of a hero and could also appear as a nerd with glasses. He has not done a bad movie and he is a fan favorite for many CMBs but I think he would be best for this. He is powerful and dramatic and not too overly used.

Hawke has done some pretty great roles where he acts as a dark leader like in Hamelet, Daybreakers, or Gattaca. He has the look of a billionaire and the acting ability of a star.
Shes a beautiful actress that used to do some great movies. Why not bring her back with a hit. In angel she acted like a bad ass and could bring that to Wonder Woman.
Scott Speedman has the look of Hal Jordan and the charisma. He was a bad ass in Under World 1 and 2 and could be the jerk as well. He is a strong actor that would do well with this role.
Bartha is most known for comedic roles in National Treature and The Hangover. So it wouldn't be hard for him to bring that to The Flash. He also shows a serious look that he could bring forward when he goes into action.Also has a geek enough look to be a scientist.
I've casted him before in my Green Arrow stories and he would be great for a cross over. He is a strong actor with some great roles in the past to prove it. He has the look and the attitude to be Green Arrow and Oliver Queen.

I know LEE will probably hate this one, but hear me out. He definitely has the look and the strength to be the king of Atlantis. He probably wont be Captain America so there's no better way to stick it to Marvel than by joining their enemy.
Simmons is a strong actor with a strong look to be Martian Manhunter. I don't think Manhunter should be too old looking but more wise and strong as Simmons is.
Hope you like and comment. Please read my stories if you haven't yet and tell me what you think.
