Michel Simon was at various times, a boxer, a boxing instructor, a right-wing anarchist, a frequenter of prostitutes, pimps and petty crooks. He was extremely well read, a talented photographer, a hypochondriac, a misanthrope, owner of a vast collection of pornography and with a reputation for unorthodox sexual behaviour which he did not bother to deny. The writer Richard Boston has stated that, "Whether or not he was a pleasant man, he was certainly a complex one, with a good deal of Boudu in him," and Renoir called Simon "a genius of an actor..."Boudu" was conceived primarily to make use of the genius of Michel Simon."
