The latest Green Lantern movie casting rumor involves THIS guy, actor Gregory Smith:
Gregory Smith is an American/Canadian actor perhaps best known for playing Ephram Brown on the TV show Everwood. Like Christian (Batman) Bale, he's a former child actor who's gone on to do quite well for himself as an adult actor.
Gregory Smith as Hal Jordan, huh? Well, I admit that he's cute -- but, GEEZ, he still looks so YOUNG to me, and still a bit baby-faced. I always imagined Hal as looking a bit more rugged, and like he was in his mid-30s. (The average age of most "new" test pilots is allegedly between 32 and 35.)
One interesting note about Gregory Smith, though -- He currently holds the record for the LONGEST on-screen kiss in American cinema history: 5 minutes 57 seconds, in the movie Kids in America (2005), over the film's closing credits.
