Okay, I've got one: Kurt Russell, who began his career as a kid and teen actor in a bunch of squeaky-clean Disney comedies, then reinvented himself with a trio of performances circa 1979-81: first as Elvis in a TV movie (considered by many to be the definitive film portrayal of The King), then as a sleazy salesman in one of my favorite films, 'Used Cars,' and especially as one-eyed Snake Plissken in 'Escape From New York.' What historical precedents are there for what Brian Austin Green is doing here? He's gone from squeaky-voiced 'Beverly Hills 90210' fifth wheel (did anyone at any point watch that show for David Silver?) to convincing bad-ass, and, along with Summer Glau, the reason I remain engaged by a show that's otherwise just slightly better than mediocre. Spoilers for last night's 'Terminator: The Sarah Connor Chronicles' coming up just as soon as I do a book report on 'Ozma of Oz'.
