 According to Kevin Brownlow (qv)s and David Gill (I) (qv)s  documentary series _Unknown Chaplin (1983) (TV)_ (qv), the first  scenes to be written and filmed take place in what became the  movies second half, in which the penniless Tramp finds a coin and  goes for a meal in a restaurant, not realizing that the coin has  fallen out of his pocket. It was not until later that  Charles Chaplin (qv) decided the reason the Tramp was penniless  was that he had just arrived on a boat from Europe, and used this  notion as the basis for the first half. Edna Purviance (qv)  reportedly was required to eat so many plates of beans during the  many takes to complete the restaurant sequence (in character as  another immigrant who falls in love with Charlie) that she became  physically ill.
