'Terminator' is back - screaming fans greet prankster

Arnold Schwarzenegger pranks fans as the Terminator but for charity.

Also to promote yet another 'Terminator' movie, Schwarzenegger visited Madame Tussauds wax museum in L.A, where he pretended to be a wax figure as fans posed for photos, then shocked them by putting his arms around them.

The highlight of the video: his confrontation with another Terminator impersonator on the Hollywood Walk of Fame.
