The movie Citizen Kane picked up the image of Xanadu. This clip is full of references to "Kubla Khan." The voiceover even calls the main character, Charles Foster Kane, "America's Kubla Khan."
Here's a video of singer/songwriter/performer David Olney reading "Kubla Khan." He gets pretty into it. Dramatic with a capital "D."
Some cool drawings based on Coleridge poems by a Victorian artist. Be sure to check out the one of Xanadu in the lower right-hand corner.
A page with a bunch of casts of people's faces. If you scroll down a little, you can see what Coleridge looked like. A little creepy, but fun.
This was the story that Coleridge included with the poem when it was published. It explains the unusual circumstances surrounding the writing of this poem.
A good quick overview of the Chinese dynasty that was founded by Kubla Khan.
