** One of the actors playing the autograph hounds (Rick Petruccelli) had a very small role in ''Film/TheGodfather''. Diane Keaton had a major role in the film.
** Janet Margolin (Robin) also played Woody Allen's wife in ''Film/TakeTheMoneyAndRun''.
* ActorInspiredElement: Music/PaulSimon felt that the script's portrayal of Tony Lacey was unrealistic. He convinced Woody Allen that he had a much better grasp on how to portray a music industry sleazeball like Tony, so Allen let Simon rewrite his own scenes.

* AllStarCast: Go back to the main page and look at the poster.
* TheCastShowoff: Diane Keaton gets to show off her singing chops in a couple spots.
* CreatorBacklash: Allen has said numerous times that he wasn't satisfied at all with how the film ended up, and is mystified at how it's constantly listed among his best works.
* TheDanza: Diane Keaton's real name is Diane Hall.
* MagnumOpusDissonance: Though frequently regarded as one of Creator/WoodyAllen's best films, Allen himself doesn't think very highly of it, only being able to see how much it doesn't live up to what he really wanted it to be.
* MidDevelopmentGenreShift: This was originally written as a murder mystery named ''[[http://en.wikipedia.org/wiki/Anhedonia Anhedonia]]''. The movie that we see is simply a romantic subplot that was secondary to the mystery. Allen's editor thought the main plot was so bad that he convinced Allen to cut it out entirely. The narration was then added in post-production, along with a few linking scenes. Many years later Allen would make ''Manhattan Murder Mystery'', a comedy starring him and Keaton that took some elements of the original ''Annie Hall'' mystery plot.
** Before ''that'', the film was intended to be a period comedy set in VictorianLondon.
* MissingEpisode: A DeletedScene had Alvy walking around New York at night with all the neon signs telling him to go see Annie in LA. Allen hated how the scene turned out so much that he threw the negative of it into a tar pit.
* ThrowItIn: The sneeze during the coke scene was unscripted, but left in because the result was so hilarious.
* WhatCouldHaveBeen: Marshall [=McLuhan=]'s cameo wasn't originally intended for [=McLuhan=]. Among Woody's first choices were Creator/FedericoFellini and [[Creator/LuisBunuel Luis Buñuel]].
* WorkingTitle: Woody Allen originally wanted to call the film ''Anhedonia'', which is the clinical term for the inability to enjoy anything. Also a fitting title, as it is the protagonist's key character trait.
