Worst Performances: Battle Beyond the Stars (1980), Chained Heat (1983), Howling II: Your Sister is a Werewolf (1985)
As inferior as she may be, Sybil Danning's presence in old-school B-movies is always a good thing. The photo above should explain why, but here's the skinny: Despite her hammy line readings, the Austrian looker built a formidable reputation within the genre film community for always going for it, "it" referring to the further lengths of scenery-chewing, recklessly showy camp. There's perhaps no better example than Howling II: Your Sister is a Werewolf, an abysmal lycanthrope sequel in which she plays immortal wolf queen Stirba as if she's starring in the trashiest Ed Wood movie imaginable.
