Harry Potter is still one of the hottest properties in Hollywood so it's only natural that after Warner Bros. announced they were looking to cast a teenage version of Jude Law's Albus Dumbledore in 'Fantastic Beasts 2' that a lot of people threw their names in the hat.
Conan O'Brien's brief casting call featured some of TV's finest actors vying for the role, some of whom didn't really understand the assignment (*cough* Nick Offerman) while others took the role and ran with it.
Unfortunately for them, they're probably not going to get the part. But God loves a trier, no?
