TORONTO - Oscar nominees Benedict Cumberbatch and Michael Shannon electrified audiences at the Toronto film festival Sunday with their portrayals of Thomas Edison and his rival in the race for marketable electricity, George Westinghouse.

"The Current War" was directed by Alfonso Gomez-Rejon, who described Edison as someone "who came from a world of spontaneous invention without really seeing the purpose for it at first, and created a purpose for something."

In contrast, he said, "Westinghouse could immediately contextualize something and see how it could be greater for society."

"The rivalry between them was interesting," Gomez-Rejon said, because of "what it said about the world and how we can, through invention and technology, leave it better than how we found it."

Edison and his team conducted the first incandescent lightbulb tests in 1879 and a few years later began broad distribution of electricity using a direct current.

Westinghouse, whose interests in gas distribution and telephone switching led him to look into electrical power distribution, saw that Edison's use of low-voltage DC had a limited range.

After reading about European AC systems, he set out to develop and market AC power systems that could distribute electricity over long distances to dispersed US populations.

He was also able to achieve greater economies of scale with the use of centralized power generation, allowing him to sell electricity at cheaper rates.

The movie also stars Nicholas Hoult as inventor and futurist Nikola Tesla. - AP
