The Big Clue That Kit Harington Could Be Returning to 'Game of Thrones'

Perhaps we haven't seen the last of Jon Snow.

In the photo, Harington is back to sporting his familiar long hair, after showing up at the U.K. premiere of the movie "Testament of Youth" back in January with a much shorter 'do. That's led to speculation that his "Game of Thrones" character, Jon Snow, may be returning to the popular drama.

Snow was killed off during last month's season-five finale.

The 28-year-old actor's hair has created a lot of excitement on social media. "This is a recent picture of Kit Harington, notice his hair. He hasn't cut it. JON SNOW LIVES," tweeted one fan.

Another post reads, "Kit Harington still hasn't cut his hair, y'know what that meeeaaaaaaannssssss (-:"
