What character have both Robert Downey Jr. and Benedict Cumberbatch played?

Iron Man can't be beat! And Downey is an Aries like me. Yeah!

I've not seen either version. I'll have to watch them to compare!

Shouldn't this be in the movie category?

The Game is Afoot!

Both of these actors are great . I like these type of stories. I am getting tired of going to the movies and just seeing special effects. We need educational good stories.. z

Tony, Cumberbatch plays a more complex version

Much better by Downey!
