"Senator Smith learns very quickly how the political machine in his state is trying to manipulate him, and he starts to fight back. They start their gears in motion to crush him however, and his last resort is a filibuster on the floor of the Senate. As long as he keeps talking and remains standing, he can hold the floor, but as soon as either his voice or his legs give out, he loses everything. This filibuster is one of the greatest David v. Goliath stories on film."
From: Mr. Smith Goes To Washington (1939 )
( If you have never watched this classic...DO SO ! I think of the character played by Jimmy Stewart every time I see and hear Fred Thompson....but that's just me. )
