The Return of the First Avenger
Fennhoff's history as Doctor Faustus in the comics is referenced in the series, with him shown reading Christopher Marlowe's "The Tragical History of the Life and Death of Doctor Faustus". Having Faustus meet Zola was intended to set up Hydra's use of mind control for the Winter Soldier program, as seen in "Captain America: The Winter Soldier". Hydra's system of brainwashing and mind control is also seen in the series "Agents of S.H.I.E.L.D.", where it is referred to as the Faustus Method.
