This macho action film about knights comes from Guy Ritchie, and it’s filled with great actors, superb historical costumes, and impressive castles and magic — what more do you need in a movie? Aside from Jude Law and Charlie Hunnam, you can also admire the performance of Aidan Gillen ("Littlefinger" in Game of Thrones), who stars here in a huge blockbuster for the first time.
