"It's fun to play the character not only because of that … Right after I did the first Terminator movie, I remember that I was offered a tremendous amount of action film roles. It set me in a direction that was exactly where I wanted to go in my career," says Schwarzenegger.

With a low budget of around $6.4 million, The Terminator raked in over $78 million in worldwide box-office receipts, paving the way for both Cameron and Schwarzenegger's march to join Hollywood's A-list.

Speaking about the latest film, Schwarzenegger reveals that the cyborg has spent more than 20 years living among humans, growing a conscience and choosing to sacrifice himself to save mankind.

Perhaps one of the biggest challenges for the former champion bodybuilder, the 72-year-old actor reveals, was the daily training regimen required for the action-packed film, which involved many fight scenes and the use of military weapons.
