Lars Ulrich says he took his latest acting role "very seriously" - but Metallica won't allow much time to expand on his side-career, as they need to constantly tour to afford all their staff and album recordings.
Ulrich was discussing his role in the HBO film "Hemingway & Gellhorn", which premieres on Monday, as a Dutch documentarian.
"I don't have big acting career aspirations, but I love dabbling in different processes," he told USA Today. "I wasn't chasing this, but I couldn't say no.
"I took it very seriously. I studied the difference between how a Dutch person would say things in English and the way I would as a Dane. Most people couldn't tell the difference, but I can. And it needed to be right."
Ulrich fans needn't worry that their favorite drummer will leave music for the film world. He still prefers recording. "In the world of music, I get to help make the decisions," he said.
So why do Metallica have to constantly tour? Kirk Hammet has explained that the band's finances means they don't have any other choice.
Unlike their early years, the band needs to tour almost constantly to pay off their studio, salaried for the crew, and stage production.
"The cycles of taking two years off don't exist anymore," Hammet told Rolling Stone (via Blabbermouth). "We were able to do that because we had record royalties coming in consistently. Now you put out an album, and you have a windfall maybe once or twice but not the way it used to be - a check every three months."
One benefit of earning a solid tour income is that the band can finance their own recordings, which leads to better royalties from record sales. "We basically take funds from wherever we can," he says. "This is a real luxury. But great things come out of this."
