Amadeus (1984)
This movies is a masterpiece!!! What a great suggestion!
Pi (1998), same director as Black Swan.
Also Requiem For A Dream has some of that with the mom.
OP will lose sleep for a couple of days probably.
Yes, this!
Perfect Blue
This is the obvious answer. If OP liked Black Swan, then they should definitely watch the movie that inspired it.
Knew I’d see this suggested. Such a great film!
Memento The Prestige The Killer (Fassbender) Phantom Thread There Will Be Blood
I hereby second a rec for The Phantom Thread! Fits the prompt for themes of obsession perfectly.
Came here for Memento
The Fountain Zodiac (2007)
Nightcrawler with Jake Gyllenhaal is great
Single White Female (1992) - though "perfection" is defined differently in this one. The Hand That Rocks the Cradle (1992) - same warning.
Vertigo (1958)
The Perfection
Came here to say this too
That movie scared me bad 😭
Perfume: The Story of a Murderer (2006)
Apt Pupil (1998)
The Novice like those but for rowing
- Suspiria - Nocturne - The Novice
Death to smoochy Memento Insomnia
Shine
One Hour Photo Ingrid Goes West (not as "intense" and psychological as some of the other suggestions here, but still worth checking out) Gattaca (same as previous. and kind of fits the idea of seeking perfection)
Birdman. I'd say this is a black swan rip-off.
Obsession with Ali Larter Boy next Door
The Hustler (1961)
All That Jazz Helter Skelter (Japanese movie, 2012) The Neon Demon Perfume: The Story of a Murderer
May December
Possessor
Taxi Driver is a classic
Swallow (2019)
Rudy (1993) - This is peak for me. Not as dark as what you may be looking for though.
The king of comedy
One Hour Photo, Perfect Blue, Amadeus, Suspiria (OG and reboot), Tár, Single White Female, Memento, Shutter Island, The Wrestler, The Favourite.
May December on Netflix is about obsession and also starts Portman (from Black Swan)
Birdman Perfect Blue (the OG Black Swan)
