Penthouse is a 1933 American Pre-Code crime film starring Warner Baxter as a lawyer and Myrna Loy as a call girl who helps him with a murder case. The film features Charles Butterworth as the butler, Mae Clarke as the murder victim, Phillips Holmes as the suspected murderer, and C. Henry Gordon as the gangster who arranged the murder. It was directed by W. S. Van Dyke and written by Frances Goodrich and Albert Hackett, based on a novel by Arthur Somers Roche. The film was later remade as the more sanitized Society Lawyer (1939), without the risqué pre-Code dialogue.
