The only man this side of Kevin Bacon who can hold a candle to Christopher Walken in the dancing stakes, Sam Rockwell has cut a rug in an impressively high proportion of the films hes appeared in, yet hes never quite managed to waltz his way to a permanent place on the marquee. Rockwell has been working steadily since the late-eighties and racked up 85 credits in his career thus far. He also excels in every film he appears in and has done since 1999, a year in which he played it for laughs in Galaxy Quest and turned stomachs as Wild Bill Wharton in The Green Mile. Since then, Rockwell has put in great performances in The Hitchhikers Guide To The Galaxy, Matchstick Men, Seven Psychopaths and The Way Way Back, and a host more diverse output to prove his ensemble prowess. He also headed up the cast on George Clooney's directorial debut Confessions Of A Dangerous Mind and can consider himself extremely unfortunate to not even receive an Oscar nomination for his outstanding work in 2009s Moon. Plenty of casual moviegoers will only know him as Tony Stark-lite Justin Hammer in Iron Man 2, which is a pity in that few parties involved in the rushed comic book sequel emerged with any real credit. A confident leading man and an ever-reliable supporting player, hopefully Sam Rockwell will find more roles worthy of his talent in the near future.
