The Danish actor's name is tricky -- but thankfully not quite as hard to master as the plot twists on his HBO show "Game of Thrones."
"I have heard every pronunciation of my name possible," he once told the New York Daily News. "The 'J' in Nikolaj confuses people -- it's pronounced as an 'I.' Sometimes they skip the end and just say Nicola, which is a girl's name. Not good."
And one last thing: Say the "W" in his last name as if it were a "V."
