You know Maisie Williams? That girl who plays Arya Stark? While she's an original cast member she wasn't one of George's original picks. He had originally picked another girl to have that spot in the cast; a pretty, blond 11 year old. The girl's parents were reluctant to sign the contract to allow their daughter to be on the show, which was putting a hold on filming. HBO was getting really antsy about it though, but George was dead set on having this girl (and "having" this girl). HBO eventually said enough is enough, and told him to forget about the girl. They instead insisted that because it was too late to start up auditions again, that he had to use Maisie, who they pulled from the auditions they were doing for another show.
The thing about George "give that loli some molly" Martin though, is that he couldn't forget about that little blond girl. He was so close to tappin' that, and it slipped out of his greasy sausage fingers. It pissed him off even more that he was saddled with that ET looking Maisie. He remembered that and would take it out on her for the entire first season. He would constantly write her the most annoying and unflattering dialogue, and generally treat her poorly while filming. That wasn't even the worst of it though, there was something far more sinister going on behind the scenes.
Early on in the show's run, there was one scene where Maisie was required to say a long list of items in a rapid fire manner. She kept flubbing the lines and laughing about it, which made George furious. He stopped executive producing for the afternoon and invited her, as well as Kit Harrington who plays Jon Snow and Richard Madden who played Robb Stark to come to his office and rehearse in private. He offered them sodas, but had slipped roofies into Maisie's drink. Before long, she was out of it, passed out on George's couch. He then went over, spread her legs and signaled to the boys.
"Well, go ahead. She's all yours."
Kit and Richard just looked confused.
"Jesus Christ, spit roast that white bitch! FUCK HER!"
Richard, raised in a strict christian home, was appalled by the idea. Kit though, wasn't too popular with girls because of his height and was all too willing to go along with it.
George tried his best to bargain with Richard, saying that if he went along with his wishes that he would make the kids stars. He'd get them their own show, movies, anything.
Kit asked if he could never kill their characters, of which Dan guaranteed.
Elated, Kit then begged Richard "Come on, man! Let's split this bitch in two! Richard, however, still refused. As punishment, George locked the door and made him watch in disgust as his friend went to town on the passed out girl, while George masturbated in the corner.
"Your going to regret this, son." the fat pervert said as he cleaned his dick with the girl's shirt. "Kit here is going to be a star, and you'll be nothing. A washed up nobody who's lucky if he gets a role in a TV movie."
For the record, thanks to Grum pulling some strings, Kit did end up getting movie roles and has been on that show for years. Richard, on the other hand, was killed off and can barely get any work, only landing roles in SyFy original movies. To this day, George makes sure of that.
