Gotham has found its Tigress. Jessica Lucas (Evil Dead, Pompeii) has joined the cast of Gotham as new regular Tabitha Galavan, aka Tigress, sister of Theo Galavan (James Frain) and half of the new villainous duo that will be introduced in Season 2 of the Fox series. Tigress is the lead enforcer for her brother Theo, the billionaire industrialist hell bent on taking over Gotham. Sexy, violent, and toting a bullwhip, she’s the opposite of her cold and calculating brother – deriving a sensual pleasure from the violence and mayhem she’s tasked with. Lucas’ casting was first reported by Deadline’s sister pub TVLine. Lucas recently wrapped a run on Fox’s Gracepoint. Her other TV credits include Cult, Friends With Benefits and Melrose Place. Lucas is repped by Gersh and Thruline Entertainment.
