Its no surprise that once it was announced that a live-action Nightwing movie was in the works that speculation on who would play the titular character erupted over the internet, One actor on lot of lists is Jared Padalecki of Supernatural fame.
The bonus is he actual is interested. He was asked on twitter if he would like to play Nightwing by a fan and this is what he said:
@DanielJFalconer I’ve always wanted to…

Padalecki already works for Warner Bros. Televison on Supernatural. He did star in the 2009 Friday The 13th, produced by New Line Cinema (WB Company) and disturbed by WB Pictures. It would seem to be a organic transition from WB TV Star on The CW to WB Movie Star. His Supernaural co-star Jensen Ankles even played Jason Todd /Red Hood in the 2010 DC animated film, Batman: Under the Red Hood. He has a built-in fan base and he isn’t so famous that you couldn’t see him in the role of Dick Grayson/Nightwing. He is also young enough at 34, to potentially star in multiple films as the character.
