He's back! The release of Terminator Genisys this week marks the return of one of the biggest names in Hollywood, Arnold Schwarzenegger. It's his fourth appearance in a franchise which has struggled to live up to the admittedly exceptional standards of its first two installments. While Arnie's post-political acting career has hardly given audiences the best there is when it comes to action movies, his legacy in Hollywood as perhaps the most successful action star of all time is well and truly secure. Movies like Predator, Commando and Total Recall are as fresh and exciting today as they were when they came out in the 80s and 90s - as well as reminding us why action films are so much better when they're R-rated. Of all the movie stars to have found a home on the Hollywood Walk Of Fame, few are so literally and figuratively larger than life. Since moving to America from his native Austria and winning the Mr. Olympia contest seven times, Arnie broke into movies before his move into politics as the Governor of California earned him the nickname, "The Guvernator". He's also a noted businessman, with a staggering $300 million net worth. It's an impressive life and career, so let's look a little closer at ten fascinating facts about Arnold Schwarzenegger you might not know.
