Harrison Ford is struggling to keep from jumping out of his chair.

His face flushes. The veins in his neck bulge. Across an ornate desk, under sharp questioning by Mr. Ford, the man in charge of Indonesia’s forests smiles wanly as he tries to explain just how he managed to allow a national park to be chopped down for the production of palm oil.

This is one of the more vivid scenes in “Years of Living Dangerously,” an award-winning documentary series that ran on Showtime this summer. Viewers — after watching wanton forest destruction earlier in the episode, and seeing Mr. Ford gently caress endangered orangutans made homeless by it — will be hard pressed not to root for him as he confronts a representative of the Indonesian government, known for its corruption.

Showtime is a premium channel, which means that many American households did not have the chance to see “Years of Living Dangerously.” That is a shame, and now it is fixable: The series has become available on streaming services like iTunes, Amazon and Vimeo on Demand, with more to follow. The series is also out on DVD for $50.
