Arnold Schwarzenegger and Joe Manganiello, his co-star in the 2014 movie 'Sabotage,' both worked in construction before they became famous. Schwarzenegger was also a bodybuilder, winning the Mr. Olympia contest seven times, before he concentrated on his acting career and became one of the most famous action stars of all time.
Schwarzengger penned the foreword in Manganiello's 2013 book 'Evolution: The Cutting Edge Guide to Breaking Down Mental Walls and Building the Body You've Always Wanted,' and wrote: 'Joe was a construction worker who worked in masonry to get by while he waited for his big break. And I was a construction worker who stared a bricklaying business with my best friend Franco to get by when bodybuilding didn't pay.'
