American theater and TV actor John McGiver was brought to Paris for the location shooting of Billy Wilder's "Love In The Afternoon" from August through December 1956. While he was there he was cast in the role of the shady American art dealer in "The Man In The Raincoat", though his French dialogue was dubbed by another actor. "The Man In The Raincoat" started shooting in October and was released in France February 1957, whereas "Love In The Afternoon", which had started filming earlier, was not released until June of that year.
