This thing has been traveling around the internet fast the last couple days. Behind the scenes footage from the making of I Heart Huckabees was leaked online showing director David O. Russell going completely nuts on actress Lilly Tomlin. Be warned, the clip features a lot of strong language. This is classic stuff.
Russell is notorious for being difficult on the set. In 1999, Russell and George Clooney nearly had a fistfight on the set of Three Kings. Not long after, an altercation occurred at a Hollywood party between Russell and director Christopher Nolan.
