NEW YORK — Last May, Stellan Skarsgård premiered his aching family drama “Sentimental Value” at France’s Cannes Film Festival.

Since then, it's been roughly nine months of red carpets, Q&As and awards shows, all leading to Skarsgård’s first Oscar nomination for best supporting actor. He even managed to squeeze in a quick trip to New York to join his eldest son, actor Alexander Skarsgård, on “Saturday Night Live” in January.

The Swedish icon admittedly gets “restless, but I’m also pretty good at not working,” Skarsgård, 74, says over coffee on a recent morning. For him, “the energy kicks in on the set. I don't sit – I still stand up or pace around for 12-hour days. It’s an endorphin kick that you thrive on.”

“His stamina is crazy; he’s an energy vampire,” Alexander tells us in a separate interview. “I was really happy and moved that Dad flew all the way from Stockholm to do ‘SNL.’ He came straight from the airport and partied all night – I had to shove him into a car at 6 in the morning."

“At the after-after-party,” his father says now, flashing a mischievous grin.
