After a day of Internet gossip and rumors, are you ready for some stimulation -- err, intellectual stimulation? Or how about just a good spanking?

Well, it's all there in the just-released trailer for David Cronenberg's 'A Dangerous Method,' which Sony Pictures Classics picked up last week for U.S. distribution.

The film looks to be a fascinating take on the intense relationship and rivalry between Carl Jung and Sigmund Freud that gave birth to psychoanalysis.

The film, written by Christopher Hampton, based on his 2002 play 'The Talking Cure,' stars Michael Fassbender as the psychiatric pioneer Carl Jung and Viggo Mortensen as his rival, Sigmund Freud.
