In the latest example of experimentation with collapsing distribution windows, Martin Scorsese's "No Direction Home: Bob Dylan" will be screened in 30 cities as part of a deal set to be announced by Emerging Pictures. Emerging will join forces with Thirteen/WNET New York for free screenings of the two-part, nearly four hour doc that screened at the Teluride Film Festival this past weekend and is also set for a screening in Toronto. It will be shown in 30 cities before its PBS airdates on September 26th & 27th and a full length DVD from Paramount is anticipated a week before the TV airdate as well.
