Elling (2001)

For reasons that I would not care to explain, this Norwegian movie was apparently its home country's biggest box-office hit.  It is a sweet and gentle film, but nothing to sock you between the eyes.  It tells of a mama's boy who is institutionalised when his mother dies (he is by now in his forties).  There he rooms with a Neanderthal who is even more lacking in social skills.  Eventually they are released to a council flat under the beady eye of  a social worker and gradually learn to cope with society, albeit in very limited ways.  Elling develops an alternate persona as the "sauerkraut poet", attaching his output to packets which he places in supermarkets, and his roommate finds his first girlfriend, even if she is heavily pregnant with someone else's child.  I'm probably making it sound droller than it really was.
