Movie action man Dwayne Johnson picked the perfect day to show off the first image of his new earthquake drama San Andreas on Monday (17Mar14) - hours after the real thing hit California.

Johnson, aka The Rock, shared the still from the upcoming Michael Bay movie with his fans on his Instagram page just hours after a 4.4 magnitude quake hit Encino and was felt around Hollywood.

Apparently unaware of the tremor, Johnson wrote, "Puttin' in a lot of hard a** work and proud to play my next role... Los Angeles Fire Department Air Squadron Rescue. Shooting starts in 4 weeks. Biggest earthquake of all time hits... San Andreas."

He made no mention of the actual earthquake.
