Dyanne Thorne is back as "Ilsa," the toughest sex kitten ever to let her pussy do the dog onscreen, in Ilsa, the Tigress of Siberia (1977). She continues her titillating portrayal of sadism, this time as the warden of a Stalinist Gulag in the early '50s. The first half of the movie concerns itself with Dyanne getting herself off with torture and sex (it takes two men to tune her motor). Then Stalin dies and she decides to cover up her prison in corpses, killing most everybody regardless of whether they were prisoners or guards. The second half of the movie opens in present day Canada, where Dyanne is running a brothel. The sex and violence goes down a notch, at least for an Ilsa movie, as she captures one of the few surviving captives from her communist past and takes him down mammary lane for some make-up torture. How can Dyanne be so hot when she's so cold?
