Watched Black Hawk Down yesterday. One of my all time favorites. It had been awhile, and every time I watch it I realize another person that has hit it big. Seriously, look at this cast.

Obi-Wan
The Incredible Hulk
Legolas
Bane
Mr. Fantastic
Lucius Malfoy
Tig from Sons of Anarchy
Ari from Entourage
Jaime Lannister (1st American role?) He was the one I just noticed.
I'm sure there are others I'm forgetting, but even this many is ludicrous. Make the same movie today with this same cast, and your casting expense would be egregious.
