[1][2][3] Bielinsky entered the film industry around 1983 as an assistant director, working under such filmmakers as Miguel Pérez, Carlos Soria and Eliseo Subiela.

Bielinsky wrote the script for the 1998 film La sonámbula, recuerdos del futuro (released abroad as Sleepwalker), directed by Fernando Spiner.

[4][2] Bielinsky directed his first film, Nine Queens (Spanish: Nueve reinas) in 2000, a crime thriller about a scam involving forged stamps.

[4] An American remake, Criminal, was produced by Steven Soderbergh and released in 2004,[1] however, receiving tepid response from critics and audience because it lacked ingenuity of the original.

A month before Bielinsky was going to present The Aura at the Edinburgh International Film Festival, he died from a heart attack in his sleep in São Paulo, Brazil, while casting for an advertisement.
