Artifact is a 2012 American documentary film directed by Jared Leto under the pseudonym of Bartholomew Cubbins. It was produced by Leto and Emma Ludbrook through their production company Sisyphus. Artifact chronicles the modern music business as it charts the legal dispute between Leto's rock band Thirty Seconds to Mars and record label EMI, which filed a $30 million breach of contract lawsuit against them in 2008, after the band tried to exit its contract over a royalties dispute. Thirty Seconds to Mars is shown working with producer Flood to create the 2009 album This Is War, meeting with lawyers between recording sessions.

Artifact had its world premiere at the 2012 Toronto International Film Festival where it received the People's Choice Award for Best Documentary. Critics praised the examination of the state of the modern music industry and its focus on the relationship between artists and record companies. The film received a limited theatrical release beginning November 23, 2013, before being released digitally on December 3, 2013.
