* AcclaimedFlop: Despite critical and awards love, the film failed to break even (grossing $32.5 million on a $60 million budget). In fact, the film's box office failure may have led to the [[CreatorKiller decline of Cameron Crowe's career]] until his 2011 comeback. Fortunately, it's been VindicatedByHistory and is now one of Crowe's signature films.
* BillingDisplacement[=/=]CoversAlwaysLie: Creator/KateHudson is not the main character. Patrick Fugit is (and Creator/BillyCrudup gets first billing). But she is nowadays almost always the first actor people associate with the movie.
* CaliforniaDoubling: The film was shot in and around Ocean Beach, San Diego, [=CA=], Crowe's hometown. Much of the film is set there, but the parts that aren't were also filmed there. The San Diego Sports Arena appears both as itself and as a stand-in for several other concert venues throughout the film.
* {{Defictionalization}}: One of the Director's Cut DVD extras was a "Stillwater" CD.
* ExecutiveMeddling: A benevolent example. Crowe wanted to include a scene where William plays the entirety of Music/LedZeppelin's "Stairway to Heaven" for his mom. WordOfGod says they couldn't get the rights to "Stairway" for the scene, but it was eventually included, without the Zeppelin song, on the Special Edition DVD. Some [=YouTubers=] have [[https://www.youtube.com/watch?v=Ra9YR1ze0w0 synced the song to the visual,]] though the DVD includes an on-screen prompt for the viewer to play "Stairway" alongside the scene.
** Crowe's original title for the film was [[NoTitle ''Untitled'']]. Humorously enough, [[http://www.imdb.com/title/tt1132193/?ref_=nm_flmg_act_22 this has since been]].
* OneHitWonder: Despite her popularity throughout the rest of the 2000s and tabloid/gossip prominence, Creator/KateHudson has yet to star in any films as critically acclaimed as this one. All of her movies since have been critically slaughtered romantic comedies.
* RealLifeRelative: Creator/CameronCrowe's mother is Mrs. Deegan.
* StarMakingRole: For Creator/KateHudson. Although far from suffering in obscurity due to being Creator/GoldieHawn's daughter, she was not known as an actress beforehand. This is the performance that earned her widespread acclaim and helped to launch her as an A-List star in her own right. Even years after her more popular romantic comedies faced heavy backlash, "Almost Famous" remains the one film of hers well-regarded today.
** Also, to a lesser extent, for Creator/BillyCrudup. It did not launch him to the same heights that Hudson reached but did bring him cult recognition. Additionally, Crudup was more well known than Hudson going into ''Almost Famous'', having ''Film/{{Sleepers}}'' on his resume at the time, so it's harder to pin this film as his SMR than hers.
* TechnologyMarchesOn: Played for a laugh. "A Mo-Jo, it's a very high-tech machine that transmits pages over the telephone! It only takes eighteen minutes a page!"
* ThrowItIn: "Do you want to go to Morocco?" "Yes. [beat] Ask me again." This was not scripted, but in fact was Patrick Fugit asking Kate Hudson to do another take of the exchange.
* WhatCouldHaveBeen:
** Creator/ElijahWood tested for William Miller.
** The role of Russell Hammond was originally meant for Creator/BradPitt. He turned it down saying, "I don't understand it enough to do it".
** Creator/JackBlack and Creator/JonFavreau auditioned for Lester Bangs.
** Creator/ScarlettJohansson auditioned for a role that was later cut.
** Creator/MichaelShannon auditioned for an unknown part. He later said it was the worst audition of his life.
** Creator/KirstenDunst auditioned for Penny Lane and came very close to getting it. Creator/ChristinaRicci also came close.
* WorkingTitle: Creator/CameronCrowe initially wanted to name the film ''Untitled'', after the style of an obscure record by a forgotten band. The studio forbade it until the Director's Cut, which was officially titled ''Untitled: The Almost Famous Director's Cut''.
* WriteWhatYouKnow: The entire film is based on Cameron Crowe's days as a teenage rock journalist.
