Interesting little situation...
This movie is currently is post-production and experiencing some troubles...mostly, it seems, with first-time director Alec Baldwin's concerns about time and control. Here's an article about this...

This is a $27M movie...has major stars (Baldwin, Hopkins, Ackroyd)...the trailer got a good response at Cannes...yet there's no official site for the film yet (contrast this to "The Hulk" which hasn't even wrapped shooting and there's already a trailer and a site).
I'd say "DanielWebster.com" is the most appealing choice of URL for this movie, particularly since this is a major actor's vanity project (see safesys' many posts on the high value of vanity names).
Since you already have a site for this domain, I'd suggest you put a very prominent link at the top of your homepage for an internal page dedicated to this movie. Copy the production info from one of the other sites (
http://us.imdb.com/Title?0263265 ), and have a link to the trailer (
http://www.ce-ent.com/comingsoon.html ). Then maybe do a little se work...
In any case, once you've set up the special movie page, I'd do a gentle pitch to this film's production company. Once they finish post-production on this film, they're going to start marketing it, and that's going to be a least a couple of million. I'd say your domain name, being the best one (devilanddanielwebster.com is just a little too long), is worth a few thousand to these guys, easy.
The one major drawback is that this film's production company (Cutting Edge Entertainment) already regged "devilanddanielwebster.com" (in 2000), and might be content to use this as their promotional URL.
Good Selling!
