When he is not taking old women to red carpet events, Zach Galifianakis is pulling out of press conferences because of phobias.

The star had to pull out of a press conference for the recent “The Hangover Part III” movie as a result of his deep fear of heights.

A rep for Warner Bros:

Zach is afraid of heights, and called into the press conference to let participants know, and made a few jokes.

The Morro da Urca in Rio media conference could only be reached by a cable car an insider reported, “Zach was too afraid to ride up.” But hunkalishous Bradely Cooper and Ed Helms were brave enough to represent the boys at any height and did so up the 220 meter mountain.

According to the NY Post there was a bit of controversy going on between the actors before the conference. Rescheduling of the press conference took place as a result of some sort of dispute between Cooper and Galifianakis at the Fasano Hotel they were both guests at.

Regardless of their domestic, the movie promises to make us laugh.
