Currently imdb sports a snazzy poster for this movie...seems to be a poster created by Turner Classic Movies, a nice image of March holding up a beaker with Hyde's face reflecting in the glass. I've never seen this image before. What's it from? I even checked Turner Classic Movies's website and the image isn't there.
shareI'd guess that it's a cover Turner did for the DVD release of the film. It's a painting, not a frame from the film, so until they come up with an official answer, I think that's the best one.
shareYes it is from TCM's "Summer Under the Stars" series from 2009.
Here is a link with the different posters. Scroll down, and the "Dr. Jekyll and Mr. Hyde" one is in the eighth row going down, in the center between "The Picture of Dorian Gray" and "Wuthering Heights".
