I don't think anyone has forgotten about Michael Keaton--y'know, being Batman and Beetlejuice and whatnot--but he did seem to fall off the face of the earth. Same thing with Kurt Russell. The last memorable roles I remember from either of those guys were from Quinton Tarantino films (Jackie Brown and Deathproof, respectively). Too bad, because I think both guys deserve to be in the movies and I for one would like to see them there. Those guys seem to have followed the path of Robert Redford--huge movie star who just stopped being in movies one day.
Bummer if true. Let's just say that I was a big fan of Northern Exposure as a kid going through puberty.
