Well i will start with a little plot summary i thought of:
The film is set just 1 year after batman is first seen, the police force sees him as a criminal, the citizens see him as a hero, Bruce Wayne has now gotten back in the public eye and is making himself out to be a normal celebrity, meanwhile a game show goes on, Edward Nigma loses by a technicality, so he gets mad and kills the host, he takes the name The Riddler and starts his own mad game with batman.
Starting with the main man himself
Michael Fassbender as Bruce Wayne/Batman
Bruce Wayne is the main character in the movie, he would be portrayed as very charismatic and almost arrogant, trying to hide the batman side of himself
Reason for casting: Fassbender is an amazing actor and he would be a great Bruce, and he could also pull off the batman's more detective side.
John Hurt as Alfred Pennyworth
Alfred is Bruce's Butler and Caretaker, he is very sarcastic and very willing to help Wayne in anyway he can
Reason for casting: i like john hurt and he can play alfred good especially the british accent.
Bryan Cranston as Captain Jim Gordon
in this film Captain Gordon will be trying to chase down Batman, but will be distracted from this by the new villain, The Riddler.
Reason for casting: i just think he's a good actor and can pull it off.
David Tennant as Edward Nigma/The Riddler
The Antagonist, he is a madman and a genius who wants to kill batman in a mental game.
Reason for casting: I love David Tennant in doctor who and i think he could play a great villain, he also has a great american accent.
Joseph Morgan as Harvey Dent
The all american, Gotham's white knight, he is a great guy who may have some secret personality issues, he is friends with Bruce and even helps out batman.
Reason for casting: Joseph is a very good actor, he always plays the bad guy though, i thought playing a nice guy might be a good challenge for him
Alice Eve as Vicki Vale
Vicki is a reporter who wants to get the scoop on batman and ends up falling for the billionaire, she also gets into trouble a lot.
Reason for Casting: C'mon she just makes a good leading lady
Eric Bana & Claire Danes as Thomas & Martha Wayne
Bruce's Parents Killed in a Flashback
and Finally young Bruce played by Max Charles, hes a really good child actor
Well thats it guys and girls, let me know what you think of my first fancast for my DC universe and i will add more later thanks! :)
