Oscar-nominated German actress Sandra Hüller is reportedly set to make a cameo appearance in Marvel Studios’ upcoming film, “Avengers: Doomsday.” While Marvel has not officially confirmed the casting, reports from The Hollywood Reporter suggest her involvement follows her name appearing on the British Stunt Register.
