Jamie Bell and Connie Nielsen have boarded Lars Von Trier‘s upcoming two-part feature, Nymphomaniac.  Per THR, “Charlotte Gainsbourg will star as Joe, a self-diagnosed nymphomaniac. Stellan Skarsgard will play Seligman, an old, charming bachelor who finds Joe beaten up in an alley. He takes her home to care for her and Joe recounts to him the story of her erotic life, from birth to the age of 50.”  The movie also stars Shia LaBeouf and Danish actors Nicolas Bro (Warhorse), Jesper Christensen (Quantum of Solice) and Jens Albinus (Idiots), Sweden’s Shanti Roney (Together) and German actor Severin von Hoensbroech (Ruhm).  Nicole Kidman and Willem Dafoe have been rumored for supporting roles.  THR currently doesn’t have any details on who Bell or Nielsen’s will be playing.

LaBeouf has said that all of the sex scenes will be for real, but the producers explain they “will be performed with the help of body doubles and visual effects.”  According to THR, Von Trier plans to release the films in both hard-core and soft-core versions with an eye towards a 2013 release.  The 11-week shoot in Gemany begins tomorrow.

A new trailer for the drama Perfect Sense has been released. Starring Ewan McGregor and Eva Green, the film centers on a chef and a scientist who fall in love just as a global epidemic is beginning to unravel. This new trailer isn’t as entrancing as the first one we saw, but it’s still fairly effective. I like McGregor and Green a lot, and the film seems to be chock-full of emotional moments. The epidemic that permeates the background of the film is played very straight, so it’s a little like Contagion with love.

Hit the jump to watch the trailer. Directed by David MacKenzie (Young Adam), the film was picked up for distribution by IFC Films but is currently without a US release date.

About a month ago we posted the first images from Perfect Sense, a Sundance 2011 entry led by Ewan McGregor and Eva Green with the cryptic logline, “A poetic and magnetic love story about two people who start to fall in love just as the world begins to fall apart.”  I think, for now, it’s best we leave it there.

Thankfully, this newly released trailer agrees with me.  It captures the pure melodrama indicated by the logline without revealing too much about the story.  So you can watch this footage and simply admire how beautifully the David Mackenzie-directed film is lit without spoiling things.  However, if you would like to know more about the plot, we’ve included new story details alongside the trailer after the jump.

Continuing our coverage of the films that will be featured at the Sundance Film Festival in January, today we bring you images from two dramatic films that will premiere out-of-competition at the festival: I Melt With You and Perfect Sense. I Melt With You stars Rob Lowe, Thomas Jane, Jeremy Piven, Carla Gugino and Christian McKay. Directed by Mark Pellington (The Mothman Prophecies), the film focuses on four lifelong friends who, during their annual get-together, realize that their lives haven’t exactly turned out the way they expected.

Perfect Sense stars Ewan McGregor, Eva Green, Ewan Bremner, Stephen Dillane, and Connie Nielsen. From director David Mackenzie (Young Adam), the film is described as a “poetic and magnetic love story.” Hit the jump to check out the images, as well as a brief synopsis for both films.  The 2011 Sundance Film Festival runs from January 20 – 30th.
