Terminator Genesis, the latest instalment in the hugely popular film series, will see Arnold Schwarzenegger return as an older version of the T-800 killing machine.

Though many will wonder how a robot can age, the star explains the logic in the most human way.

According to Schwarzenegger, though the robots in the science fiction movie are made of metal, they are covered with live human skin which is ageing with time.

"The way that the character is written, it's a machine underneath. It's this metal skeleton. But above that is human flesh. And the Terminator's flesh ages, just like any other human being's flesh. Maybe not as fast, but it definitely ages... Terminator deals a lot with time travel, so there will be a younger T-800," the former governor of California told MTV.

Though there is not much information about the plot of Terminator 5, it is reported that actor and bodybuilder Aaron V. Williamson will play the young T-800 in the movie.

On his social networking pages Williamson posted the news that he was playing the Terminator but later deleted the post, Movie Web reported.

"Thanks to an amazing team of people who help me get better each week, both physically & creatively, I'll be playing a T-800 (Terminator) in the upcoming production Terminator: Genesis. I'm extremely grateful & motivated as this new chapter begins to take shape," Movie Web reported the actor as saying.

According to a report by Breathcast, the movie will star Jai Courtney as Kyle Reese, while Game of Thrones star Emilia Clarke will play the popular character Sarah Connor and Jason Clarke will play Sarah's son John Connor.

The website also reported that the film will feature two T-800 Terminators: the younger one will be controlled by Skynet while Schwarzenegger's will fight against the all-controlling artificial intelligence.

Terminator Genesis will arrive in cinemas on June 26, 2015 in the UK and July 1, 2015 in the US.
