Back to the Future Part III

Back to the Future Part III (1990) is Robert Zemeckis's sci-fi adventure comedy you can watch online on iFILM — the third and final chapter of the Amblin Entertainment trilogy, starring Michael J. Fox and Christopher Lloyd.

A 1955 newspaper tells Marty McFly that Doc Brown was shot dead in 1885, just days after sending his letter from the Old West. Marty digs the DeLorean out of a mine shaft and goes back to find him. What greets him is a frontier town, a trigger-happy outlaw named Buford "Mad Dog" Tannen (Thomas F. Wilson), and a lovestruck Doc who has no interest in going home — because schoolteacher Clara Clayton (Mary Steenburgen) just changed his plans. To get them both out alive, Marty has to hijack a steam locomotive at full speed.

Zemeckis shot Parts II and III back-to-back; the two films landed in theaters just seven months apart, in 1989 and 1990. Turning the finale into a Western gave the trilogy a clean, distinct ending — and a pair of genres no one expected the DeLorean to visit. Watch Back to the Future Part III (1990) online on iFILM.
