I know he's not a movie star yet but what do you think of Corey Stoll ?
He's very handsome in an unconventional way and crazy talented IMHO.
His IMDB credits lists four very interesting projects : the adaptations of American Pastoral and The Seagull, big budget new Matthew McConaughey Gold and (I know...) the 2016 Woody Allen movie.
I don't know, he's just so interesting to watch.
