Jim Sturgess told OTRC.com that filming "Cloud Atlas" had a huge impact on his life.
"The film really affected me. It sort of changed my life. It was such a big experience, do you know what I mean? And I met so many amazing people while we made the film and I'm going to be so sad to let it go, once the film is given to the people," Sturgess told OTRC.com host Rachel Smith at the film's Los Angeles premiere on October 24. "But yeah, it certainly starts making you think about your time on this planet and every action that you make and the reason that you write a song or paint a picture - whatever you put out there doesn't disappear. It kind of lives on."
"Cloud Atlas" is based on a 2004 book by David Mitchell. It has six interconnected stories, including that of a journalist, played by Berry, who investigates alleged corruption at a nuclear power plant in 1975 and a tribesman living a primitive life in a post-apocalyptic future.
Other stars in the film include Susan Sarandon, Hugo Weaving and Hugh Grant. "Cloud Atlas" was directed by Tom Tykwer, Andy Wachowski and his sister Lana Wachowski.
When asked about the most challenging part of the film, Sturgess said that it was, "not being able to laugh at Tom Hanks while he was leering down at me, dressed as Dr. Goose, with a big ginger beard probably... looking right up his nose half the time."
The 34-year-old actor spoke particularly highly of Hanks, who took much of the cast under his experienced wing, even off the set of "Cloud Atlas."
"Tom set the tone really, for the film. He was such a great guy to be around," Sturgess said of Hanks. "We were in Berlin for a long time and he would hold film club nights and we would go over to his place and watch films and he would order tons of pizza. He's a good guy, you know?"
In addition to traveling through space and time, Sturgess also had the opportunity to portray characters of different races and social positions.
Sturgess rose to fame after portraying Jude in the 2007 musical film, "Across the Universe." The British actor has also appeared in films like "The Other Boleyn Girl," "21" and "One Day."
When asked what his all-time favorite film was, Sturgess referred to one by "Monty Python" and "Fear and Loathing in Las Vegas" filmmaker, Terry Gilliam.
"The film that I always go back to, and there's a bit of that in 'Cloud Atlas' too, is a film called 'Time Bandits' by Terry Gilliam. It's got great, big ideas, but it's a really playful film and I used to watch it loads and loads and loads, when I was a kid and then you can watch it as an adult and enjoy it in the same kind of way."
