There aren't too many films out there dealing with poetry. One of my favourites though is Slam. This came out several years ago now, but was a vibrant film about the power of poetry to change people's lives. A performance poet working in prison helps one of the inmates to develop as a poet and as a person.
The other one that springs to mind is the film about Samuel Taylor Coleridge, that I can't remember the name of. It was not factually accurate but had a wonderful dreamlike quality and portrayed Taylor Coleridge as a real environmental visionary.
Any other excellent films about poetry?
