The King of Devil's Island star told HeyUGuys that he is hoping to fit the sequel and the new Lars Von Trier film into his schedule.
"I will try to combine Thor 2 which starts in August and goes to the end of December with the new Lars Von Trier film," he said.
Skarsgård played Dr Erik Selvig in the original Thor, a role he reprised for The Avengers. The character serves as a mentor to Natalie Portman's Jane Foster, who will have an extensive role in the sequel.
Kat Dennings has remained tight-lipped about the possibility of reprising her Thor role of Darcy Lewis in the Alan Taylor-directed follow-up.
Thor 2 is scheduled for release on November 15, 2013.
