Matt Damon Shirtless, Shows Off Hot Body Filming New Bourne

Matt Damon is looking hotter than ever.

Just check him out in a photo that was posted on Twitter earlier today from the first day of filming Bourne 5, the upcoming fifth installment of the Jason Bourne series.

In the pic, the 44-year-old actor is shirtless with his chiseled chest and abs on full display. He’s covered in dirt and his hands are wrapped in rags. It appears the pic was snapped when he was shooting a fight scene.

“First day of principal photography complete and happy to report, BOURNE is back! #Bourne2016,” producer Frank Marshall tweeted along with the pic.

The film will mark Damon’s first time back as Jason Bourne since 2007’s The Bourne Ultimatum.

Joining Damon on set is his personal trainer Jason Welsh.

“Matt is absolutely the best client anybody could ever hope for,” Welsh told E! News last month at the opening of his new L.A. fitness studio Rise Nation. “He is hard working and he is funny as hell. So we keep it light, but we work really, really hard.”

Damon also shows of his body in The Martian, his new film in which he plays an astronaut stranded on Mars when his fellow crew members believe he was killed during an unexpected storm on the red planet.

The Martian, which will premiere at the Toronto International Film Festival on Friday, will be in theaters Oct. 2.
