Los Angeles production house Experiential Supply isn’t letting the city’s trick-or-treating ban dampen Halloween. The company last week launched “Haunt-o-ween L.A.,” an interactive drive-through attraction in Woodland Hills.The Haunt-o-ween event has transformed the parking lot at the Westfield Promenade mall at 6100 Topanga Canyon Blvd. into a drive-through spook alley that includes a tunnel with 1,000 Jack-O’-Lanterns, a pumpkin patch, in-vehicle trick-or-treating and a drive-up theater screen that will display yet-to-be-announced footage. Tickets cost $70 a car, with up to eight people allowed in each car. Costumed staff will be masked and will stay 6 feet from guests, who must remain in their vehicles.FX, a cable television channel owned by Burbank’s Walt Disney Co., funded the construction of a black-light tunnel to promote FX’s Emmy-nominated vampire comedy series “What We Do in the Shadows.”
