Good genes run in the family! Liam and Chris Hemsworth share family photos as they reunite for 'The Dressmaker' premiere in Melbourne... but where's brother Luke?

They're the two best-looking brothers in showbiz. 

And Liam and Chris Hemsworth showed off the source of their good genes by posing with their parents for a few family photos on social media. 

The family were reunited for the Melbourne premiere of Liam's new Aussie film, The Dressmaker.

The only member of the brood missing was big brother Luke, who was nowhere to be found.

In the snaps - taken after the premiere - the Hemsworth men looked smart but relaxed in their red carpet ready suits.

Meanwhile, mum Leonie wore loose white pants and a matching top, and added some glam to her simple ensemble with a sparkly jacket.

Leonie is a well-known red carpet regular, and has been attending events with Liam for years. 

'Another strange family portrait to add to the mix,' Chris wrote on Instagram. He then acknowledged his brother's absence, hashtagging: '#wheresluke?'

Liam didn't mention Luke on his account, simply captioning his photo with a friendly: 'Thanks for coming, legends!'

The Dressmaker is based on a novel by Rosalie Ham of the same name.

A-lister Kate Winslet stars as Myrtle 'Tilly' Dunnage - a dressmaker who returns from Europe to her small Australian hometown to take care of her ailing mother.

Liam plays likeable larrikin Teddy McSwiney with whom Tilly unexpectedly falls in love.

Speaking at the premiere, Liam revealed to AAP that the character reminded him of his grandfather.

'He reminded me a lot of my grandpa. That was the biggest thing that attracted me to the role,' he admitted.

The Dressmaker is currently showing in selected cinemas.
