Self-Made Celeb Movie Promotions - Ben Stiller, Robert Downey Jr., Jack Black for Tropic Thunder (VIDEO)

Actor Ben Stiller knows the tremendous power of the internet and viral videos so he attempted to create his own to promote his new movie, Tropic Thunder. With the collaboration of Iron Man’s protagonist Robert Downey Jr. Kung Fu Panda star Jack Black and Stiller’s internet savvy teenage nephew, the actor created a juvenile but hilarious video that has Downey Jr. squabbling with Stiller’s nephew and repeatedly crotch-kicking Jack Black among other things.

As of this writing, the video, which was posted to YouTube 3 days ago, has only received some 10,400 views.
