Whoo, Nelly. The infamous fights between David O. Russell and Lily Tomlin on the set of I Heart Huckabees have finally found their way to the internet. No secrets in this modern age, guys, and definitely NSFW!
I find this clip to be a fascinating window into the often frustrating atmosphere that takes over film sets, and goodness knows that good art often comes from tension and stress. Lily Tomin's own response to the arguments is pretty classic as well. "...I don’t have to keep up some great pretention [that] I’m the most dignified, eloquent, elegant, perfect, smart-thinking, kind, generous person. I’m just a plain old human with a whole bunch of flaws." Amen! (Thanks to Little Jimmy Thang for putting that link in the comments)
