Playing the part of the arrogant knight in the critically acclaimed HBO production, Danish actor Nikolaj Coster-Waldau believes he was the first to recognise the similarity.
"The funny thing is… I think I was the first to say that when we shot the pilot," revealed the 41-year-old actor in a video interview from London. "When I put the armour on for the first time, I said, 'That's Prince Charming from Shrek'."
Answering a few exclusive questions from Yahoo!, Coster-Waldau asserted that he had no qualms playing the villain in the medieval fantasy series.
"I've played all kinds of roles [in my career] and of course the ones that stick out are the most successful [ones], and right now that is Game of Thrones," he said, adding that he loves his character for its well-written role.
When asked about his character's dubious love affair with his sister, Lannister laughed it off by admitting that "the incest thing is, of course, weird".
"But the way I see it… he fell in love with this girl who just happens to be his sister. [And] I can relate to falling in love with someone," he added.
In the three-minute long interview, Coster-Waldau also teased about what audiences can look forward to in the upcoming season of the adventure-drama.
"There's a scene that was shot that is one of my most favourite scene ever in any job," he confessed. "Episode 7 is my favorite episode, I can say that much."
