David Bradley is one of those actors who, even if you don't know his name, you have most probably seen his face. He has appeared on such popular TV series as Broadchurch and Game of Thrones, he guested in two of the Cornetto trilogy films and, failing those, he starred in nearly every Harry Potter film as grumpy Hogwarts caretaker Argus Filch. In case his appearing on this list didn't tell you, Bradley has also turned up in both Doctor Who and the Marvel Cinematic Universe. While he first appeared in Captain America: The First Avenger, credited as the Tower Keeper, he later made a bigger splash in Doctor Who - first, as the despicable Solomon in Dinosaurs On A Spaceship and then as William Hartnell, the First Doctor himself, in the terrific docudrama about the show's beginnings An Adventure In Space And Time. Clearly this famous caretaker takes care to appear in all your favourite franchises.
