After the film had been pulled from theatres due to poor tickets sales, Peter Bogdanovich wrote an open letter, printed in newspapers throughout the country, apologizing for the quality of the film.
The standard practice when filming a musical is to have the performers sing the songs in a studio and when they film the songs being sung, they move their lips to a play back of the already recorded tune. This musical was filmed with the performers singing live as the camera rolled. That caused many delays and technical problems.
This was the first movie musical since the early 1930s to have its musical numbers recorded directly while being sung rather than having the cast lip-synch to a previously recorded score, the innovation of Douglas Shearer that revolutionized the production of musicals in the era of the early talkies. There was no technical reason for the music to be recorded directly, and it is one of the reasons that the picture is considered to have failed. Critics attacked director Peter Bogdanovich for his hubris for what they considered an extremely ill-advised stunt, seeing how his leads (with the exception of trained singer Madeline Kahn) were little known for their musical abilities.
Peter Bogdanovich toyed with the idea of playing the role of Pritchard himself so he could star opposite his then-girlfriend Cybill Shepherd. However he offered the role to Elliott Gould who turned it down before Burt Reynolds accepted it.
This movie was amusingly dubbed "The Man Who Loved Tap Dancing" - a play on words of the title of the Burt Reynolds movie made two years earlier entitled The Man Who Loved Cat Dancing.
This movie's title At Long Last Love is taken from one of the Cole Porter songs of the same name. The song 'At Long Last Love' was written by Porter for his 1938 musical, 'You Never Know'.
Cole Porter started writing the lyrics to the song 'At Long Last Love' whilst in pain waiting for medics to arrive after being in the accident which made him disabled.
The art & set direction / production design of this film is evocative of the 1930s style and kind as created by art director and production designer Van Nest Polglase.
Burt Reynolds just prior to this film had starred in a movie called Hustle. Many years after this picture was made, its director Peter Bogdanovich directed a film called Hustle.
Peter Bogdanovich once said of this film he directed: "Studios bury more films than the public or the critics. Fox gave up on 'At Long Last Love' instantly. A six million dollar film was written off while it was doing well because their lawyers told them they could make more money that way."
The tagline "IT'S THE TOP!" from this movie's main poster is actually derived from one of Cole Porter's song titles, "You're the Top". The tagline also evokes the earlier musical, Top Hat.
'Halliwell''s has described this film as "An attempt to recapture the simple pleasures of an Astaire-Rogers musical" [See: Fred Astaire ; Ginger Rogers.
