Jai Courtney in Terminator Genisys (2015)

Jai Courtney joined yet another film franchise with his starring role in this year's Terminator Genisys. Jai took on the role of Kyle Reese, who is sent back in time on his original mission to protect Sarah Connor, only to discover that the timeline has been fractured, leading to a whole new past. One of the best things about the Terminator universe is that time travel must be done in the nude. Jai strips down for several scenes during the film, including a few brief nude moments. He also gets a few opportunities to show off his great chest.
