Peter Bogdanovich has stated that Woody Allen watched the movie three or four times during its theatrical run, and later credited the film for inspiring Todos Dizem Eu Te Amo (1996).
Peter Bogdanovich considered playing Pritchard so he could star with his then-girlfriend Cybill Shepherd. He offered the role to Elliott Gould who turned it down before Burt Reynolds accepted it.
Peter Bogdanovich once said of this film, "Studios bury more films than the public or the critics. Fox gave up on 'At Long Last Love' instantly. A $6 million film was written off while it was doing well because their lawyers told them they could make more money that way."
Cole Porter started writing the lyrics to the song 'At Long Last Love' while waiting for medics to arrive after being in an accident which left him partially paralyzed.
The versions of the film that have played on cable for decades are not the version that was released to theaters in 1975. Peter Bogdanovich re-edited the film after its disastrous first run. The new version ran three minutes shorter and was called the "TV version." Another version, which was streamed on Netflix, was an unofficial version of the film, designed to closely match the test screening edited by Bogdanovich before 20th Century Fox forced him to re-cut it. Bogdanovich claims that he did not authorize the Netflix version, and was unaware of the cut's existence until over three decades after the film's release. He later learned that it was assembled by an archivist at Fox, a huge Cole Porter fan who followed the making of the film.
