 Notable examples include Professor Marvel in "The Wizard of Oz" and Professor Drosselmeyer (as he is sometimes known) from the ballet "The Nutcracker".Also, the magician played by Christian Bale in the film, "The Prestige", adopts 'The Professor' as his stage name.A variation of this type of non-academic professor is the "crackpot inventor", as portrayed by Professor Potts in the film version of "Chitty Chitty Bang Bang" or the Jerry Lewis-inspired "Professor Frink" character on "The Simpsons".
