Rabbit Hole looks like its going to be critically successful but the film deals with a depressing subject. I wouldn't expect a huge box office run but it could possibly surprise to the upside depending on awards show buzz.
I Love You, Philip Morris is scheduled to go wide January 7th. It is a Roadside release so most of the benefit flows to LGF. The film hasn't gotten great reviews and the subject matter is not broadly appealing. It has also not done very well in limited release, I would think it might be in question whether or not it goes wide.
From Prada to Nada comes out later in January. It looks like it is targeted to the Spanish market which has been hard to crack for LGF. I wouldn't expect much from it.
After that the next big movie would be The Lincoln Lawyer which comes out in March. This one actually looks like it has some potential.
So all in all I would say that the winter slate is not that strong.
