The first two acts lead me to believe I'd be in for a real bloodbath between Henry Fonda and Cliff Robertson but the last 20 minutes answered my question as to why I hadn't heard of this movie before. The Best Man is worth the watch, don't get me wrong. The dialogue, acting and photography are all great. Just don't expect a mind-blowing payoff.
Alot of these movies came out during this period, but this one I liked, Fonda was his usuall great character and Robertson came across as an arrogant politician whose lack of principals finally catches up to him.
