Maybe you've heard of Game of Thrones? Probably the biggest worldwide phenomenon since Harry Potter, it featured incredible graphics, an intense plotline, and a star-studded British cast. The final episode was the most-watched finale in HBO's history.

Each of the actors on Game of Thrones has become wildly popular — even those with minor roles or those who lasted just a few seasons. It's hard to forget the face of a character who burns his own daughter alive or feeds her abuser to his own dogs!

However, every cast has its divas and GOT is no different. Here are eight Game of Thrones actors who have acted like jerks in real life, and 12 who are total sweethearts.

20 Sweetheart: Gwendoline Christie

Just like Brienne of Tarth, Gwendoline is kind and fierce. She took the Internet by storm earlier this year, by wearing an Iris van Herpen dress to the premiere of season 8. In April, she also told Harper's Bazaar that she "turned bright red in the face" when she filmed her final scenes for GOT.

19 Jerk: Isaac Hempstead Wright

Isaac might have won the Iron Throne, but he has some more work to do if he wants to be as famous among fans as his on-screen sisters. He made some people mad with his comments on the ending of Game of Thrones, calling it "ridiculous" for people to be upset about the ending.

18 Sweetheart: Maisie Williams

It's easy to see why Maisie Williams is a fan favorite. Although she's been in the spotlight since nine years of age, she still seems extremely nervous around the press. Her shy personality and genuine kindness make it easy for people to like her.

17 Jerk: Alfie Allen

Publicly shaming a fan probably isn't the best way to show that you know how to banter. In 2017, Alfie embarrassed a fan who posted a photo explaining how proud she was to ask Allen for a picture. He responded: "Actually your mum asked for you."

16 Sweetheart: Kit Harington

Thankfully, this heartthrob (and the sole reason some fans watched GOT) is just as sweet IRL as his character, Jon Snow. He was like a brother figure to his on-screen sisters during filming, and maintains a humble attitude to this day.

15 Sweetheart: Rose Leslie

As someone who is married to one of the most attractive men alive, Rose Leslie does a great job of keeping her cool. She is consistently adorable in interviews, talking about her husband, Kit Harington, and what their first meeting was like.

14 Jerk: Aidan Gillen

It has been reported a few times that Aidan Gillen has been a jerk to his fans when they walked up to him in public. While numerous reports of this kind are uncommon, it still may hold true that Aidan is not a people person.

13 Sweetheart: Nathalie Emmanuel 

Millions of people were heartbroken when Missandei died in GOT; luckily, we could still catch a glimpse of Nathalie in the Four Weddings and a Funeral miniseries. Nathalie is constantly on her Instagram, thanking fashion designers and friends and fellow cast members for everything they do for her.

12 Sweetheart: Kristian Nairn

It's easy to see why Kristian Nairn is a sweetheart. He looks like a giant teddy bear. On the set, he carried Isaac Hempstead Wright's character, Bran, on his back so much that he said it gave him back problems.

11 Jerk: Pedro Pascal 

Oberyn was a sultry seducer on GOT, but Pedro himself has said he was a jerk on former TV and movie sets, and in other jobs that he had before becoming an actor. Apparently, it caused him to get fired from a few places.
