'Game of Thrones': Kit Harington Reveals Injuries He Got on Set

— -- After playing Jon Snow on "Game of Thrones" for years now, you can imagine all the thousands of fan letters and emails that Kit Harington has received since the hit show began.

If the 28-year-old actor hasn't gotten back to you just yet, don't worry, he's getting to it.

Harington stopped by ABC News this week to talk about season 5, which begins on Sunday. The British actor said he's happy his character has stayed alive this long and that with the show drifting from the books a bit, no one can tell how long they are going to be in the script.

"There are deaths this year, like every other year," he said. "There doesn't seem to be a formula [for who gets killed]."

As for his millions of fans, Harington said, "I do get fan mail. I apologize, I'm terrible at responding to it. I've got it all there at home."

When is he going to write back? "One day. I'm going to, I've just been busy over the last few years!"
