Yoko Ono has allowed some rare footage of John Lennon to be seen for the first time.
The archive material, which is featured in new documentary 'The US Vs John Lennon',was given to two filmmakers by Lennon's widow.
Directors David Leaf and John Scheinfeld got access to Ono's home movies, wedding photographs and unfinished films.
The film focuses on the period between 1966 and 1976 when Lennon was an anti-war activist and had trouble qualifying for US citizenship.
Ono said: "Of all the documentaries that have been made about John, this is the one he would have loved."
Director Leaf: "It's definitely a forgotten story. The vast majority of people who lived through that period and knew something about the Lennon case haven't thought about it in a really long time. For anyone born since then, it's probably an unknown story."
The film has it premiere at the Venice Film Festival, which takes place between August 30 - September 9.document.write(unescape('\04564%6F%63um\145%6Et.%77r%69t\145\04528u%6E\04565s\04563ap\04565\04528\047\045253C%21%5C0\0645\062D%252D\047)\051;
