Brad Pitt was spotted in London on Oct. 14, looking very handsome with his new silver gray hair. According to E!News, Pitt was on location, filming his latest Netflix movie titled “War Machine.” The 51-year-old star wore light gray army fatigues with combat boots, an attire he donned for his army general role in “War Machine.”

Netflix’s new satirical comedy is said to be partnered after the controversial U.S. general Stanley McChrystal, who led the U.S. armed forces in Afghanistan. The movie is also inspired by Michael Hastings' book “The Operators: The Wild and Terrifying Inside Story of America's War in Afghanistan.”

Pitt was also seen spending quality time with his youngest children, twins Knox and Vivienne, while on-set in London. 

“War Machine” is just one of the projects that Pitt has lined up for 2015. The “Fight Club” actor stars in the upcoming movie “The Big Short” which is a movie adaptation of Michael Lewis’ book titled “The Big Short: Inside The Doomsday Machine,” according to Deadline. The film is set to be the American Film Institute’s closing night gala film set on Nov. 12. The movie will then open on limited cinemas in Dec. 11, before doing a wide release in Dec. 23. “The Big Short” also stars Christian Bale, Melissa Leo, Marisa Tomei, Steve Carell and Ryan Gosling.

Meanwhile, Pitt also acted alongside wife Jolie in the upcoming movie “By the Sea.” The two played a married couple in the film, which Jolie also directed, who struggles through relationship issues. In an interview with Vogue for the magazine’s November issue, Jolie said the film is “not autobiographical.” She continued “Brad and I have our issues… but if the characters’ were even remotely close to our problems we couldn’t have made the film.”

“By the Sea” is set to hit movie theaters on Nov. 5.
