K-19: The Widowmaker - Cpt. Alexei Vostrikov

This movie is often overlooked, but is an important entry in Harrison's filmography.

Harrison plays a Russian nuclear submarine captain in the 2002 thriller, and impressed everyone on set through his professionalism.

Recalling the actor, his co-star Peter Sarsgaard said: “None of us knew what the hell we were saying, 'Shut down No 3 generator, blah-blah-blah.' Do you give up on that or do you try to find some meaning for yourself? Well, everything has meaning for Harrison Ford. I never saw him throw something away.”
