I have been seeing previews on TV of the new film The Lookout (opening today), starring Joseph Gordon-Levitt, and I must say that Mr. Gordon-Levitt has grown into quite a fetching man. I also noted that he somewhat resembles Heath in his facial features, and when I mentioned this, my sister agreed. Probably won't be seeing the film in theaters, but looking forward to seeing more of Gordon-Levitt in the future.
Incidentally, an online acquaintance of mine thought that Gordon-Levitt was superb in Mysterious Skin, and thought this performance was even more remarkable than Heath's in Brokeback Mountain, even though he conceded that Heath's performance was excellent.
