Hangover star Justin Bartha has revealed that he regrets having gone to Thai sex clubs for research of the film’s sequel after seeing some "disgusting" things over there.
The actor said he feels so "ashamed" about what he saw there but refuses to talk about them for fear of offending people.
The actor, who plays Doug in The Hangover Part II, admitted he and co-actor Ed Helms went to great lengths to research their scenes.
"I saw some dirty (stuff) in Thailand that got burned into my eyes. I honestly can't say what because it is so disgusting I feel ashamed for going. I shouldn't have gone," the Herald Sun quoted Justin telling Bullett Magazine.
The 32-year-old admitted it's one of his biggest regrets, and issued a stark warning for anyone considering following in his footsteps.
"It is so far beyond what people think," he said.
