Well, I have. And I love the first movie and the Donner cut of the second. But.. As great as Christopher Reeve is in both roles, I still don't buy that, realistically, no-one would just look at Superman's face and go "Hey Clark." One of the things I liked the most about All-Star Superman was the invoking of this, where I got the feeling that EVERYONE at the Daily Planet knew Clark was actually Superman but said nothing, and yet Luthor was completely unable to link the two.
