The “Star Wars” actor is currently filming the adventure documentary series “Long Way Up” with his friend Charley Boorman. The pair, who previously circumnavigated the globe on motorcycles in “Long Way Round” and rode across Africa in “Long Way Down,” have apparently undertaken the journey from the tip of South America to southern California for the latest installment, using vastly different bikes than before.

The team was also accompanied by prototypes for the upcoming Rivian R1T, a 4x4 electric pickup set to go into production next year with backing from Ford and Amazon and a range of more than 400 miles per charge.

Considering they have 10,000 miles or more to travel and not much of a charging infrastructure for much of the way, exactly how they’re going to pull this off with electric vehicles is unknown.

A Harley-Davidson spokeswoman told Fox News Autos the company had no comment on the reports, while Rivian has not yet responded to a request for comment, but Boorman did say that there would be "surprises" and a "twist" on this trip, according to Motorcycle News.

A date for the premiere of the series has not been announced.
