Movie role & possibly leaving
One Direction.
Which sounds like the
Right Direction. (A noun if you think of it as a people name!)
But, obviously not
Slaine, because there is no
Slaine film

It's something
else (http://www.msn.com/en-au/entertainment/movies/christopher-nolan-wants-harry-styles-for-movie-role/ar-AAgGuuM?ocid=spartandhp).
I still reckon he'd be the ideal young version of the
Barbarian. (That's a noun, right!) When he did the best stuff he ever did. He could pass for younger version of himself well considering that young men in those times reach that platue of growth & maturity where they don't change much until they reach that other platue of middle age. (Something I noticed about
Richard's Chamberlain role in that series
The Thorn Bird's He reminds me of that famous activist/musician
Bob Geldolf. There is a very strong resemblance there & somebody here once commented that some early poster picture that
Simon Davis did of him before he was officially commissioned to draw/paint him for the
Prog. (I'm pretty sure it's thing!) looked -words to the effect- a lot like him!
Not that I could find that picture on the internet to show you. You may know which one I am talking about. I could almost imagine
Mr Geldorf as the venerably aged former wanderer retelling his early life in retrospective episodes with help of some
CGI or rubber-suit to beef him up. because I'd doubt he'd weights training to fit the shape of the older
Slaine. He'd be built like a ex-
Marine or
Aussie-Life-Saver. Not that don't doubt his entertainer's capacity for fitness.

In his younger days
Not sure if a activist would really like to be axe wielding man-man either.
