Joseph Gordon-Levitt played an alien on 'Third Rock From the Sun' back in the day, but he's just downright subhuman in the teaser for his new indie drama.

The 'Inception' star -- and future 'Dark Knight Rises' baddie -- is hell-bent on trouble as homeless anarchist Hesher, the titular character in writer/director Spencer Susser's feature film debut.

Living in his van until he meets vulnerable 12-year old T.J. (Devin Brochu) -- whose mother just died, rendering his father (Rainn Wilson) emotionally crippled and incompetent -- Hesher takes the kid under his wing. For better or worse.
