Thought of that too... would be awesome. Make it so Whedon!They used the name and nothing else. In the Ultimate comics, yes, they were shape-shifters, but we didn't see a single bit of that in the movie.
Also, a thought occurred to me. Marvel recently won back the rights to both Ghost Rider and Daredevil. I would love to see a court case episode and suddenly Matt frigging Murdock appears to represent.
