The film, directed by Christopher Bell, was one of the most buzzworthy at January's festival.
Bigger focuses on the rampant steroid scandals that have dominated the headlines lately as well as the American obsession with winning at all costs. Bell draws from his own personal experience as the brother of two siblings who used performance-enhancing drugs.
Produced by Alex Buono, Tamsin Rawady and Jim Czarnecki, the docu also features interviews with such athletes as Barry Bonds, Floyd Landis, Carl Lewis and Ben Johnson.
Magnolia, the theatrical and home entertainment distribution arm of the Wagner/Cuban Cos., will release the film this year in the U.S. It will be broadcast on HDNet after its release.
"It's informative, fascinating and hysterical -- all the things a movie about steroids should be," Cuban said.
