The moving images behind a weapons ban

''Postcard From Lebanon'' (above) ''sheds light on the cluster bomb problem,'' says filmmaker Jocelyn Ajami. (BILL HARPER)

When Jocelyn Ajami set out to make a film about Lebanon after the 2006 war between Lebanon and Israel, she didn't think she'd end up making, as she puts it, "a tool to campaign against cluster bombs."

"The film focuses on a 10-day visit, six weeks after the war, by a group of Americans," says the Caracas native who now lives in Boston's Back Bay.

"It shows the destruction of Lebanon and sheds light on the cluster bomb problem," she says. "Lebanon catalyzed the process toward drafting an international treaty banning cluster bombs. I use the film to shed light on the wider problem all over the world. Bombs we dropped in Laos in 1964 are still exploding."

Ajami will present the North American premiere of "Postcard From Lebanon," her 36-minute video, at the Museum of Fine Arts on Wednesday at 6:30 p.m.

A post-screening discussion will cover the adoption of an international treaty last May that bans the use of cluster bombs. This week has been named "Global Week of Action Against Cluster Bombs."

The documentary will also be shown Nov. 8 at 2:15 p.m. For further information about the film, contact the MFA at 617-267-9300 or mfa.org/film, or visit Ajami's website at www.gypsyheartproductions.com.
