Actor Rob McElhenney has filed to legally change his name to “Rob Mac” due to concerns about pronunciation in foreign business negotiations. The creator of It’s Always Sunny in Philadelphia and star of the show, McElhenney wants to make the change despite initial reservations about altering his family’s heritage. He discovered that some relatives had already altered their surname across generations to simplify spelling and pronunciation.
McElhenney has been using “Rob Mac” during business talks in South America, where he believes his multi-syllabic name will be difficult for locals to pronounce. The actor’s wife Kaitlin Olson is also adjusting to the new moniker, but their children are reportedly unhappy about it. McElhenney made the decision after considering the impact on his professional and personal life. His shortened surname brings him closer to his Always Sunny character, Mac.
