Baron Bomburst is a fictional character and the primary antagonist in the film Chitty Chitty Bang Bang. The character did not appear in Ian Fleming's original novel; it was created by the film's screenwriter, Roald Dahl. Played by Gert Fröbe, Bomburst rules the Barony of Vulgaria together with his wife, Baroness Bomburst. In the stage and film versions, he is a spoiled brat who refuses to grow up. He is also vindictive, pampered, self-centered, and incredibly effeminate. In Broadway versions the character has been played by Jonathan Freeman, Ed Dixon, and Marc Kudish.
