[2][3] While attending NYU, Miller was a founding member of the short-lived Bullstoi Ensemble theater company along with Hoffman and fellow actor Steven Schub.

[4] It was during this time that Miller, Hoffman and Schub made a pact that if any of them ever won an Academy Award, their entire acceptance speech would consist of nothing but barking.

As described by Wheeler Winston Dixon, the film documented the "tough life of a tour guide on a New York City bus", and was made using handheld digital cameras.

In his review for Rolling Stone, Peter Travers called the film "a new peak" for Miller, who "takes a scalpel to the privileged worlds of Olympic sports and inherited wealth.

[14][15] Miller has directed 6 performers to Academy Award nominations: Philip Seymour Hoffman and Catherine Keener for Capote, Brad Pitt and Jonah Hill for Moneyball, and Steve Carell and Mark Ruffalo for Foxcatcher.

As of 2018[update], Miller appears to be working on a documentary on the topic of future technologies featuring contributions by academics and experts in the field such as Danny Hillis, Ray Kurzweil, Kevin Esvelt and Sherry Turkle.

He won the Best Director Award (French: Prix de la mise en scène) at the 2014 Cannes Film Festival for Foxcatcher, which was also part of the main competition for the Palme d'Or.
