I have to pitch another Must See film, with the very apt tag line of "Connection is everything." 

The Visitor is one of my top three films of SXSW 2008 (the other two being very, very different). It's the Thomas McCarthy's follow up to The Station Agent, another character study that finds uses the complexity of it's characters to build a poignant and realistic story that's both personal and topical.

Walter (Richard Jenkins, Six Feet Under) seems to have died with his wife, and only exerts himself to avoid interaction.  He's reluctantly forced to go to New York for a conference, only when he gets to his apartment, he finds it occupied by two strangers. And one act of kindness changes his life, and theirs, forever.

It's a story of connections and culture, with powerfully understated performances. Jenkins, one of the most underrated actors of our times, is sublime to watch as Walter is forced to navigate the world around him.

All of the cast is outstanding, with incredible chemistry; 
Haaz Sleiman's Tarek has such joy you'll find yourself smiling along with him.  Danai Jekesai Gurira's Zainab, Tarek's lover, plays counterpoint with her reserve.  But it's Hiam Abbass' Mouna who steals every scene she's in, with her incredible dignity.
