With Allen Iverson’s professional career coming to what seems to be the quietest of all conclusions,  “Hoop Dreams” director Steve James‘ documentary, “No Crossover : The Trial Of Allen Iverson”, produced for ESPN’s “30 On 30” series, will premiere at Austin’s Paramount Theatre on Sunday, March 14 (11:00am) as part of the South By Southwest Film Festival.  It’s unlikely the subject of the film will be making an appearance, what with his daughter’s health being a primary concern, but rest assured Austin has some of the nation’s finest medical facilities.
