Ketchup Entertainment has acquired Evan Jackson Leong’s “Linsanity” and will release the documentary on Oct. 4.

The Jeremy Lin doc, which premiered at Sundance, will launch in Boston, Los Angeles, New York and San Francisco along with 10 to 15 other cities.

Film follows Lin‘s life from his childhood in Palo Alto, Calif., to his meteoric ascent to stardom in early 2012 with the New York Knicks in the National Basketball Assn., giving rise to the term “Linsanity.” The film was an official selection at South by Southwest this year and screens Wednesday at the opening night of the Asian American International Film Festival at Asia Society in New York City.

The project was financed by 408 Films, and produced by Christopher Chen/Endgame Entertainment, Brian Yang/408 Films and Allen Lu. “Linsanity” started filming in 2010, while Lin was a relatively unknown basketball player at Harvard University.

Justin Chang of Variety gave the film a positive review:  “An example of long-term documentary filmmaking paying off in ways few could have anticipated, ‘Linsanity’ energetically recounts Jeremy Lin’s astonishing rise to NBA stardom.”
