Matt Murdock AKA Daredevil - Bradley Cooper
He seems like a good fit, in Limitless he plays more of a serious role than in the Hangover, and i think he could make a good Daredevil.
Elektra Natchios AKA Elektra - Olivia Wilde
She also seems like a good fit for Elektra, and i think she could pull off Elektra.
Wilson Fisk AKA Kingpin - James Gandolfini
I'm not sure if this is a common choise for Kingpin or not, but to me it seems to make sence. I think he'd make a great Kingpin.
Lester Pointdexter AKA Bullseye - Zachary Quinto
Probably my favorite pick on the list, and to me it makes perfect sence. Anyone who watched Heroes knows that Zachary is great at pulling off a pure psycho. He played Sylar, a serial killer, and i think that he could really transform the character of Bullseye and make him really great.
Jack "The Devil" Murdoch - Tate Donavan
Tate did a pretty good job of pulling off a troubled father in the O.C. a few years back, and Jack Murdock is also sort of a troubled father. I think Tate would be a good father for Matt Murdock.
Ben Urich - Jack Coleman
Just from the picture they look kind of similar, and Jack (who was also in Heroes...) seems like a guy who would be a good Ben Urich.
Franklin "Foggy" Nelson - Jason Segel
Probably an unusual choice and even i'm admitting that, but Foggy is kind of like the comic relief and Jason is really funny. That's why i'd pick him to play Matt Murdock's best friend.
Hope you enjoyed my fan cast!
