As a child, Arnold Schwarzenegger's mother began having concerns over his fascination with bodybuilding, but young Arnie's obsession was to propel him from his humble origins as an Austrian farm boy to one of the world's most popular action heroes.
Born in 1947 and growing up in an isolated village, Arnold got into bodybuilding working out five hours a day as a ticket to a better life, eventually winning the Mr. Universe title at the age of 20 in 1967, and repeating the feat another four times in a row. Then, after scooping the Mr. Olympia accolade on no fewer than six occasions, he turned his attention to pursuing the American dream. Arriving in the US in 1968 with $20 in his pocket, he got off to an inauspicious start.
Arnold Schwarzenegger's debut
"Nobody's ever made it with that big a body or that bad an accent or that long and foreign a name. You in the movies? Stop it! You're killing me!" laughed his agent. Nevertheless, after changing his name to Arnold Strong and with his voice dubbed by another actor, Arnie landed his first role in no-budget flick Hercules In New York. It was a less than spectacular debut which sent him back to the weights room.
"I decided right then that I wanted to weave myself right into the fabric of America. I wanted to become a citizen. I wanted to work hard," he says. The first steps were to set up a mail-order business, buy some real estate and get himself a bachelor's degree in business and international economics. His next break came in 1977, appropriately enough with a vehicle entitled Pumping Iron.
Arnold Schwarzenegger's movie career
But it wasn't until he was cast as the knuckle-headed, muscle-bound hero in 1982's Conan The Barbarian that his box-office drawing power was first demonstrated. The sword-and-sorcery blockbuster was followed two years later by a sequel, and in the same year, he teamed up with director James Cameron to make The Terminator playing a killer robot from the future. Unencumbered by challenging lines, the role seemed tailor-made for Arnie, who was to mint gold in the 1991 follow-up, Terminator 2.
Throughout the Eighties he became a well-oiled money-making machine for the studios, churning out a slew of big-budget action pictures including Commando, Predator and The Running Man. Then, in 1994, he surprised fans accustomed to his bulging biceps with a bulging waistline when he played a pregnant man in Junior. He had been steadily branching out into comedy, and his dead-pan comic delivery proved almost as popular with moviegoers as his shoot-em-up swagger.
Alternating action movies such as Total Recall, co-starring Sharon Stone, with lighter fare such as Twins, he cleverly muscled in on the varied and bankable roles that eluded screen rival Sylvester Stallone. In 1986, Arnie married into American royalty when he tied the knot with TV journalist Maria Shriver, of the Kennedy clan, with whom he has four children. It was a match that surprised many, given Arnold's penchant for Republican politics.
Arnold Schwarzenegger turns to politics
During the summer of 2003, he announced that he would run in the October elections for the Governor of California. When his victory was subsequently announced on 7 October, he declared: "I will not disappoint you. The answer is clear. For people to win, 'politics as usual' must lose."
In January 2007 he was sworn in as governor for a second term, which he completed in 2011, cementing what many thought to be an unlikely career in politics.
Arnold Schwarzenegger's personal life
The Hollywood star and his ex-wife Maria Shriver first met in 1977, when he was asked to appear at the Robert F. Kennedy Memorial Tennis Tournament, which was attended by various members of the Kennedy family.
In his recent three-part docu-series, Arnold, which dropped on Netflix in June, Arnold touched upon the start of his romance with Maria. "I really fell in love with Maria, not because she was a Kennedy but because she had an extraordinary personality. I could see that little rebel in her. I wanted to escape from Austria, she also wanted to escape. That was the beginning of Maria and I."
The couple welcomed four children together: Katherine, 33, Christina, 31, Patrick, 29, and Christopher, 25.
In 2011, after 25 years of marriage, Arnold and Maria filed for divorce following allegations of Arnold’s extra-marital affair with his housekeeper Mildred Baena. In an open Q&A in 2014, Arnold stated he was least proud of "the mistakes I made that caused my family pain and split us up".
The Terminator star confessed that during his fling with Mildred in 1996, their affair resulted in the birth of Arnold's fifth child, son Joseph Baena. These days, the father and son have a close relationship, and Joseph even attended the premiere of his latest TV project, Fubar.
Joseph told E! of his father: "He's an amazing father. He's a great person to look up to and he's the smartest man I know.
"It's been a great journey and he's always been so supportive of whatever I do. So, I'm just really grateful to have a dad like him."
