And the Australian hotties all have acting in their genes.
Luke is best known for his role as Nathan Tyson in Aussie soap Neighbours, and will next star in the Australian war film, The 34th Battalion.
Liam, best known for bringing Gale Hawthorne to life in The Hunger Games franchise, is also hard at work. He is currently filming Independence Day: Resurgence and the final installment in The Hunger Games series hits theaters on Nov. 20.
But Chris' brothers were not the only ones who appreciate his acting as Stone Crandall, an up-and-coming anchorman. His wife of five years Elsa Pataky was right by his side at the premiere too.
Chris joked with ET about his wife's reaction to him being well-endowed in the film: "Well that's why we got married maybe."
And while he has a sense of humor about it, co-star Christina Applegate recently shared with ET that Chris was serious about his prosthetic penis scene.
"It could have been vulgar," she explained. "Someone would have messed that up, because they would be thinking, 'This is so funny what I am doing with my thing, and I am going to be really, super funny with it.' He wasn't. He was playing it as if he was fully clothed."
She also shared that his abs were a constant topic of discussion on set. "'Come on, that looks so soft. What moisturizer do you use? That's incredible.' We all would watch and be like, 'Mhm. Amazing. Wow.' Men, women, children, animals, everyone stopped," she recalled.
Talk about a movie tease!
