Star Wars' Oscar Isaac says filming Guillermo del Toro's Frankenstein was "the most fun" he's ever had: "It's such dark material, but was approached with so much joy"

Oscar Isaac as Victor Frankenstein in Frankenstein.

Mary Shelley's Frankenstein isn't exactly renowned for its japes and joie de vivre. While Guillermo del Toro's adaptation very much leans into the Gothic horror side of the creature feature, Victor Frankenstein actor Oscar Isaac has revealed just how much he reveled in the fun he was having on set.

"It was the most fucking fun I've ever had in my life," a grinning Isaac tells SFX magazine, which features It: Welcome to Derry on the cover and hits newsstands on Wednesday, October 8.
