Stormare starred in Ingmar Bergman's production of Hamlet; Hilary DeVries of The Christian Science Monitor wrote: "in the electrifying lead performance by Peter Stormare, Hamlet is, for all his Angst-filled poses and dark glasses, no hamstrung cliche but Denmark's only ballast between the debauched Claudius and the fascistic Fortinbras.
