Dana Carvey is Garth Algar.
I think the main resamblance is the small chin. But there is quite and age difference. And if you look at them both about 20 years ago, there is not too much of a resemblance. And I think most people remember a younger edward norton
(didnt know the opposite was the case, that he does NOT want to be called ed... maybe qm doesnt lke him and does it on purpose for fun?)
I think you could say that only for kerr and pattinson. All the other names you hear about even if you have never seen a movie with them. (well no movies for blair and jobs..)
