Javier Bardem doesn't know how to use a computer.
The 43-year-old actor - who has 20-month-old son Leo with wife Penelope Cruz - admits he struggled in some Skyfall scenes, in which he plays cyberterrorist Raoul Silva, because he knows nothing about technology.
However, his incompetence was hidden by clever camera angles.
"Cyberterrorism - I don't know what that means myself because I basically cannot send an email," Bardem said.
"That's like a whole different world to me. I'm so behind the technology these days. It's kind of scary.
"That's why Sam [Mendes, director] put the camera behind me when I was at the computer."
Bardem also admitted he was "lost" when it came to the scenes with firearms because he was clueless about the weaponry.
"I'm lost in that, too. I didn't even know what mine was called," he told the USA Today newspaper.
"For the most part, I just put in some earplugs and just shoot."
