Nor were they the only cast members to portray their characters convincingly. I was genuinely chilled by Faysal Ahmed's half-crazed, gun-toting Bilal. I wanted to cry for Barkhad Adbirahman's young, out-of-his-depth Little B.
The tension that all four pirates managed to recreate, alongside Tom Hanks, rendered this an entirely gripping movie.
What made it even more believable was that the dialogue between them was all Somalian. There were no subtitles either. Yet it really didn't matter. The Somali actors made it comprehensible through their body language, actions and expressions, without ever falling into the trap of being too blatant.
After a while, you even forget that you can't speak Somali. You're right there with them.
Yet I may have skipped too fast past Tom Hanks to get to his co-stars. Yes, we do anticipate perfection in his performance, but that isn't to take away from what he pulled off in this movie. There were scenes there which made me ache with wanting to comfort and/or rescue him.
Prepare to be moved emotionally in a way that you don't expect with action movies. They are all that good.
