3. Harry Potter And The Goblet Of Fire
David hasn't just left his mark on one of the world's most formidable fantasy franchises, you know. He's actually left it on a grand total of four (what have YOU done today?), since he's also been in
Star Wars and is currently filming a new Marvel series for Netflix. Back in 2005 he appeared in "the one that started it all" as he headed to the big screen as the scheming Barty Crouch Jr. in
Harry Potter and the Goblet of Fire. A pure blood wizard and devoted Death Eater skilled in the execution of the Unforgivable Curses (so named because they're unforgivable - who knew?!), Barty got tongues wagging - and in more ways than one - when he took on the guise of Hogwarts' Defence Against the Dark Arts teacher, Mad-Eye Moody, to ensure that Harry won the Triwizard Tournament for reasons that become clear if you watch the drama unfold. Things happened and there was stuff and shenanigans but rest assured that Barty got his comeuppance in the end. A brilliant villain, though, and the film's true main antagonist.
