The Wedding Party

The most prominent film matching the title is Brian De Palma's 'The Wedding Party', filmed in 1963 but not released until 1969. Under the copyright laws in effect at the time (the 1909 Act as amended), US works published between 1964 and 1977 were granted automatic renewal, but they still required a valid copyright notice under 17 USC §405. For 'The Wedding Party', no evidence of a copyright registration from the time of release exists in the US Copyright Office records (CCE) or the post-1978 online database. Furthermore, the film is widely documented as having fallen into the public domain due to publication without the mandatory copyright notice. It has been distributed for decades by numerous known 'public domain' labels including Alpha Video, Reel Enterprise, and United Home Video, without legal challenge. The film's status as public domain is also explicitly noted in standard reference works such as the 'Film Superlist' and is a well-known trivia point regarding the early careers of Robert De Niro and Jill Clayburgh, who made their debuts in this film.
