Poor Zach! He couldn't attend a press conference for the final 'Hangover' movie because it was on the top of a mountain!

Zach Galifianakis has made it pretty clear that he's afraid of heights. Well, at least to those who know him pretty well. While in Brazil the cast of the "Hangover 3" were asked to attend a press conference on the top of a mountain. The only way to the top: cable car. Zach said that he could not make the trek up to the top because of the scary ride that was required. Warner Brothers had him call to apologize and explain and he even cracked some jokes.
