Back in January, Harington -- who had revealed that he is contractually obligated to keep his hair long for the duration of the show -- appeared, with shorter hair at the premiere of his movie Testament of Youth. The fact that he has now grown his hair back has sparked speculation that he will reprise his role as Jon on the fantasy drama series, reports aceshowbiz.com.

Addressing his character's fate on the show, Harington said in June: "I'm quite dead. It's over for Jon Snow - at the very least, he gets to join his family and kin and leave this terrible world behind."

However, his co-star Emilia Clarke, who plays Daenerys Targaryen, believes there is a chance that Jon would return to the upcoming season six.

"There are some helpful people there, who could bring Jon back to life. If I had to bet, I would say it's a 50/50 chance," she said in an interview.
