Kit Harington agreed to star in 'Spooks: The Greater Good' because it felt "relevant" to his own life.
The 28-year-old actor - who stars alongside Peter Firth and Jennifer Ehle in the British spy film - said he was eager to work on the movie because it's so distinct from the other projects he's been working on lately, including the popular fantasy drama series 'Game of Thrones'.
He explained: "One of the major reasons why I really wanted to take this role, not only because it had an exciting script, it had pace, it was fun.
"But also I've spent a lot of time in a fantasy realm or in a very archaic place in a lot of the work I've done on screen. So for me, this is a time when I'm still enjoying action sequences."
Kit admitted it was "refreshing" for him to take on a different type of role.
He said: "I still enjoy the physical aspect of acting and doing my own stunts and this way I could hold a gun and to read a script and speak dialogue which is a bit more relevant to who I am and who I am in life; it's quite refreshing."
'Spooks: The Greater Good' is available now on Blu-Ray and DVD, courtesy of Entertainment One.
