11. Solomon Lane (Sean Harris)

Solomon Lane is probably the smartest Mission: Impossible villain ever. The rogue MI6 agent disillusioned with the global power structure was always one step ahead of Ethan Hunt, an agent so capable, he’d previously infiltrated both Langley and the Vatican without being detected. From the moment he appeared onscreen as the man who’s infiltrated Hunt’s mission delivery system and trapped him, we knew we were witnessing a rare villain. He framed the IMF, manipulated CIA double-agent August Walker (Henry Cavill), and formed the shadowy Syndicate of former agents. Beyond being evil, he sounded evil, with a gravelly whisper that made every threat feel like a dark premonition. He was so good at being bad that he was the villain for two separate Mission: Impossible movies, making him one of the most invaluable baddies in the franchise’s history.
