3. Chris O'Donnell - Dick Grayson/Robin

When he first appeared in DC comics' Detective Comics - Dick Grayson was a trapeze artist with his parents, forming "The Flying Graysons." He was very young - in grade school - definitely not in his twenties, stealing cars and mouthing off. He was presented in this more swarthy fashion in 1995's Batman Forever as portrayed by Chris O'Donnell. Fans of Batman will recognize aspects of Robin's other incarnation - Jason Todd and Tim Drake - in the Batman Forever presentation of Dick Grayson. Still, casting a 25 year old O'Donnell to play the role originated by a child is unforgivable. Not quite as unforgivable as the next entry on the list however . . .
