The 'Second Chance' actor - who rose to fame on British soap 'EastEnders' before finding success in Hollywood in the Fox series - is set to star in the movie adaptation of the popular game 'World of Warcraft' but revealed he used to get paid to play the game and had never been happier.

He said: "It was the happiest (job), I'll tell you that. All I did was sit down in my underwear, order food in and play computer games for 18 hours and get fat and I was deliriously happy while doing it."

Nowadays the 32-year-old heartthrob is too busy with acting to keep his old job up and has a string of movie credits to his name - including movies 'Pacific Rim' and 'Hot Pursuit' alongside Hollywood starlets Sofía Vergara and Reece Witherspoon.

However, he confessed that old habits die hard and still finds time to fit in a few hours of game-play here and there.

Rob told People: "I still play... I played it professionally for a long time. It was my job 18 hours a day to play that game at one point."
