Although Black Swan was directed by Darren Aronofsky and Birdman was helmed by Alejandro González Iñárritu, it’s pretty easy to see similarities between the two Oscar-nominated (Birdman won the Oscar for Best Picture too) films. Miguel Branco noticed the similarities and created this video showing it off side by side.
Branco writes:
New York City — two artists, two opening nights, two rival figures, and one center stage. Alejandro G. Iñárritu’s “Birdman” bares many striking resemblances to Darren Aronofsky’s “Black Swan,” in terms of plot, characters, and on-screen imagery. Having seen both films beforehand is highly recommended. Spoilers [in 4k!] ahead.
