Both his brothers are actors as well

Chris Hemsworth was born on August 11, 1983, in Melbourne, Australia. Surfing was his No. 2 passion — which his siblings also shared — but Hemsworth knew that his first love was acting. After attending Heathmont Secondary College, the aspiring star snagged minor roles in television shows Down Under. Hemsworth has one older brother, Luke, and one younger brother, Liam. Both his brothers are actors as well. 
Hemsworth followed in the footsteps of other famous Aussies like Heath Ledger, Isla Fisher, Simon Baker and Naomi Watts by becoming a regular on the soap opera Home and Away. In 2007, after three seasons of playing character Kim Hyde, he headed stateside to continue his entertainment career.
It didn't take long for the actor to make it onto the American silver screen when he appeared in J.J. Abrams' 2009 remake of Star Trek. His part as Captain James T. Kirk's dad may have been small, but it was enough of a performance to lead to a huge Hollywood opportunity.
Hemsworth auditioned for the lead in the superhero film Thor. He went up against some stiff competition, including younger brother Liam. But director Kenneth Brannagh chose the older Hemsworth to play the Norse god in the 2011 flick opposite Oscar-winners Natalie Portman and Anthony Hopkins. This box-office success elevated Hemsworth to A-List status. 
The following year, he became Thor once more in The Avengers. Hemsworth suited up as the Norse god for a third time in 2013's Thor: The Dark World, and he went on reprise this popular character in Avengers: Age of Ultron (2015), Thor Ragnarok (2017), Avengers: Infinity War (2018) and Avengers: Endgame (2019).
An ability to bring in big movie crowds, especially female fans, helped the handsome actor land other leading roles besides his work as Thor. He starred in Snow White and the Huntsman (2012), with Kristen Stewart, and later returned to the role in The Huntsman: Winter's War (2016). In between, Hemsworth appeared in Star Trek Into Darkness (2013) and worked with iconic director Ron Howard for Rush (2013), a real-life car racing story. The actor teamed up with Howard again for the shipwreck tale In the Heart of the Sea (2015).
