The stakes are high, and quite pointy, in Dracula, A Comedy of Terrors. In this jocular take on that jugular-loving creature of the night, blood is sucked, true love is tested and vanity finds a way to survive in the soul of a monster who ironically cannot cast his own reflection in a mirror. Bram Stoker’s 1897 gothic tale provides the groundwork, but the spirit of Mel Brooks and Monty Python, and the ghost of Charles Ludlam, lift the evening to its batty heights.
