Who are Viggo Mortensen’s heroes? Ask him, and he doesn’t hold back. That’s what we learned when, after a recent interview, we sent the actor some follow-up questions via e-mail. His answers range from Mahatma Gandhi to Thor, Jesus of Nazareth, Jesse Owens, the crew of Apollo 11, Greta Garbo, Louis Armstrong, Noam Chomsky, Lao Tzu, Anna Akhmatova, Queen Margrethe II of Denmark, Luis Bunuel, Margaret Bourke-White, Leonard Cohen, and Larry Bird.
