The 41-year-old actor moved away from his 'mockumentary' format for his latest big screen offering "The Dictator", which was filmed as a scripted comedy instead of featuring interviews with real people who had been duped by Cohen's character disguises, reported Deadline.
Cohen now says he might not be able to go undercover convincingly anymore after shooting to international fame with 2009's "Bruno" and 2006 movie "Borat: Cultural Learnings of America for Make Benefit Glorious Nation of Kazakhstan".
"There probably are places (I could go to film another spoof) but the reality is... When you make a movie like that, you want to make sure that the people you're interviewing are deserving targets.
"So, you don't just want to interview some doorman at a hotel; you want to interview the incredibly wealthy guests at the penthouse, high-ranking politicians or people who are threatening. The problem is it is definitely challenging, especially now with Twitter and Facebook. It's very, very hard to get away with," Cohen said.
