If top body Dona Speir were a pro basketball player, she would be what is known as "a franchise player." Such a baller can ensure the profitability of an entire franchise with just his own exceptional talents. Dona is such a baller. Spier's exceptional talents include breasts as big as her head and just as visible. She also has the smooth, muscled legs and firm, ripped glutes of a person who makes her living with her physique. Her face is framed in a mane of brightly cast blondness. She is a franchise package. Since 1987, as super secret agent Donna Hamilton, Speir has been the go-to gal in director Andy Sidaris's flashy series of spy-chick erotic thrillers. The highly successful, often imitated, never duplicated Sidaris formula can be distilled to bombs and boobs and beaches and Bond gadgetry and hot tubs that double as think tanks. The intangible that pulls it all together? Dona Speir.
