Wiki says
Pandaemonium is a 2000 film, directed by Julien Temple, screenplay by Frank Cottrell Boyce. It is based on the early lives of English poets Samuel Taylor Coleridge and William Wordsworth, in particular their collaboration on the Lyrical Ballads (1798), and Coleridge's writing of Kubla Khan (completed in 1797, published in 1816).
Much of the film was shot on location on and around the Quantock Hills in Somerset.
