Not content to appear in two of history's biggest blockbuster franchises, Armitage went for a third with a small but crucial part as Heinz Kruger in the early Marvel Cinematic Universe entry Captain America: The First Avenger.
Though it's always dangerous to generalize too broadly about these things, given The First Avenger's World War II setting, you would be correct in guessing that Kruger is not one of the good guys. Instead, he's the assassin sent by Red Skull (Hugo Weaving) and Hydra to kill the scientist Abraham Erskine (Stanley Tucci), and the first to get a taste of what Steve Rogers (Chris Evans) can do with his new abilities.
Kruger completes his mission and steals a vial of the super-soldier formula shortly after Rogers undergoes the procedure that transforms him, but his attempted escape by stolen taxi and hidden submarine is thwarted when Rogers runs and swims him down, showcasing just how effective Erskine's method was. Faced with capture, Kruger kills himself Wellington Yueh-style by biting down a false tooth containing poison, getting in one of the MCU's first "Hail Hydra's" before his death.
