Of course, we know Chris Hemsworth, star of Marvel's Thor and The Avengers. Then there's Liam Hemsworth, best known for playing Katniss Evendeen's best friend, Gale Hawthorne, in The Hunger Games and being Miley Cyrus' fiancé.
Now meet Luke Hemsworth.
The eldest of the Hemsworth brothers (right) joined his Aussie siblings at the premiere of Chris' new racing drama, Rush, at the 2013 Toronto Film Festival Saturday night. The trio walked the red carpet together and posed for pics looking pretty spiffy in dark suits.
At 32, Luke was the first to get into the acting biz when he snagged a role on the Australian soap opera Neighbours and has been a mainstay on Oz TV ever since.
His big break opened doors for 30-year-old Chris, the middle child, and 23-year-old Liam, the youngest, both of whom followed in his footsteps and appeared in Neighbours before eventually catching Hollywood's attention and going on to international stardom.
Now Luke is seeking to emulate their big-screen success with roles in the Australian war film, The 34th Battalion opposite Lost's Emilie De Ravin Vinnie Jones and Stephen Lang, and the upcoming detective thriller The Reckoning.
In the meantime, Luke and Liam were on hand to show their support for Chris, who stars in Ron Howard's biopic of Formula One star James Hunt's merciless rivalry with fellow driver Niki Lauda as the duo sought to win the 1976 World Championship at Fuji in Japan.
