She's best known as Aunt Petunia in the Harry Potter films, but Fiona Shaw is actually a respected London stage actress who was a late bloomer to both film and nudity. She was already in her thirties when she made her big-screen debut in Sacred Hearts (1985). Then her sharp, mature beauty made its own belated, full-frontal debut in the historical drama Mountains of the Moon (1990). Her sexy hair-waxing scene (trust us) got us all wanting to sniff this Petunia. Our erections only got greater when she stripped down again in For the Greater Good (1991). Fiona's finery is mainly still reserved for the stage, but this Irish vixen's next booty will be appreciated by many young fans who already have a crush on their favorite aunt.
