"It's a very challenging story and I like a challenge," notes Mortensen, "Since his wife's death, Daru's living in the past, he's running away from life and Mohamed helps him realise that he doesn't want to do that anymore.
"I like this historical period in North Africa and this particular situation," he continues. "I also thought of other colonial situations, the conflict between other supposed civilising societies, whether it be in North America or in South America where I was raised, in Argentina. The consequences of that clash are felt for generations and generations. It takes a long time to get past the damage on both sides."
Perfecting his French for his first French-speaking role, and learning Arabic, proved much harder for the Spanish-resident multilingual actor.
"I speak far better French in the film than I normally do," he concedes. "I also had to change the accent I learned when I was young, which is more of a Quebec sound. I had to learn Arabic from scratch and it helped that I knew Spanish, as there are certain sounds that are not so different. I went to Algeria before we started shooting and spent some time there."
Jauja follows a father and daughter who venture from Denmark to Patagonia, where the girl elopes with an Argentinian only for Dad to track them through the wilderness.
Mortensen is back on horseback, roaming Argentina's rural north, where he holidayed as a child. "I copied my father, who speaks Spanish with a thick Danish accent, for the character. It was helpful that I had such strong connections with the culture, the language and the landscape."
