Liam Hemsworth scored his first audition at age sixteen and appeared on the Australian TV series Home and Away (1988) and McLeod's Daughters (2001) before taking on a recurring character role on the soap opera Neighbours (1985). Roles on TV shows The Elephant Princess (2008) and Satisfaction (2007) followed before Liam moved to the United States to pursue a big-screen career.

After suffering two setbacks - his character was written out of the script for The Expendables (2010) days before filming and he lost the title role of Thor (2011) - Liam was cast opposite Miley Cyrus in the Nicholas Sparks drama The Last Song (2010). Liam appeared in Cyrus' music video "When I Look at You." Following that film's modest commercial success, and the attendant press coverage of his rising career, he was almost immediately thrust into leading man status, and was cast as Gale Hawthorne in the big-screen adaptation of the best-selling novel The Hunger Games (2012). Following the blockbuster success of that film, Liam nabbed a number of roles, including a supporting part in The Expendables 2 (2012) and leading roles in the war drama Love and Honor (2013), the crime drama Empire State (2013), and the thriller Paranoia (2013). He reprised the role of Gale Hawthorne in The Hunger Games: Catching Fire (2013), The Hunger Games: Mockingjay - Part 1 (2014), and The Hunger Games: Mockingjay - Part 2 (2015), played a hero fighter pilot in Independence Day: Resurgence (2016), a period Australian in The Duel (2016), and a romantic comedy archetype opposite Rebel Wilson in Isn't It Romantic (2019).
