Jacob Elordi's drastic weight-loss for Aussie POW drama

Australian actor Jacob Elordi says the drastic weight loss he endured for his role in the new prisoner-of-war drama The Narrow Road to the Deep North was made bearable by support from the rest of the cast.

"It was a very calming experience to do it with all the lads," he told journalists on Saturday at the Berlin Film Festival, where the Australian TV series is screening out of competition.

"There was something quite profound that happened in that it wasn't a complete torture," in part because it brought him and his co-stars closer together.

Elordi, 27, is best known for his role as a high school football player Nate Jacobs in HBO's edgy teen drama series Euphoria, also played Elvis Presley in the film Priscilla and a wealthy university student in Saltburn, which saw him nominated for a BAFTA.

Elordi stars as the young medical officer Dorrigo Evans in the TV series adaptation of the 2014 Booker Prize-winning novel of the same name by Richard Flanagan.

The epic Australian drama set after World War II, spans several periods in Evans' life, including an affair with his uncle's wife in 1940, his time in a Japanese POW camp in 1943 and his later success as a surgeon in 1989.

The five-part series is due to be released on Amazon Prime Video in Australia, New Zealand and Canada on April 18.
