When you’re the star of a multimillion-dollar franchise and the former Governor of California there’s really only one way to spend your free time: by pranking the good people of your hometown.

• Mathias Cormann’s Schwarzenegger moment
• Remake kingdom: has Hollywood lost the plot?

The actor and body builder hit the famous Madame Tussauds Wax Museum in Hollywood to have a little fun in the name of charity.

Raising money for children’s wellbeing foundation After-School All-Stars, Arnie dressed up in full T-800 garb to pose as his famous Terminator character.

Unsuspecting fans wanting to snap selfies with Arnie’s likeness had the fright of their lives when he came to life, cracking jokes and posing for photos.

A particular highlight: when the real Schwarzenegger came face to face with an impersonator on the Hollywood Walk of Fame.

Later this year, the Austrian-born star will appear in Terminator: Genisys, a reboot of the 80s classic.

See the hilarious stunt in the video below.
