BURBANK, Calif. -- Buena Vista Home Video will back four rental titles with a "Bonus Dollars" sales incentive program. The titles are "Sister Act 2: Back in the Habit," which releases July 13; "My Father the Hero," streeting on July 20; and "Blank Check" and "Cabin Boy," both of which release July 27. The program is a part of a summer marketing plan that will deliver over 750 million consumer impressions, said Kelley Avery, vice president of marketing. Retailers earn the "Bonus Dollars" by purchasing multipacks of some titles, and can apply them to the purchase of others.
