Colombian actress Sophia Vergara (“Modern Family”) is one of the world’s most beautiful women. But, regrettably, there may come a time when the voluptuous 38-year-old stunner will need to be put out to pasture with the likes of Kim Cattrall, Julia Roberts, and Madonna.

But, don’t worry. There is another.

Sandra Vergara is Sophia’s 24-year-old sister and the newest face in DreamWork’s upcoming remake of director Tom Holland’s classic vampire-thriller Fright Night. The aspiring starlet will play magician-turned-vampire-killer Peter Vincent’s (David Tennant) girlfriend and assistant.

Directed by Craig Gillespie (Lars and the Real Girl) and penned by Marti Noxon (“Buffy the Vampire Slayer”), Fright Night is set in Las Vegas and stars Anton Yelchin (Terminator: Salvation) as protagonist Charley Brewster, Imogen Poots as his girlfriend Amy, Colin Farrell (Ondine) as the vampire Jerry Dandridge, Christopher Mintz-Plasse (Kick Ass) as Charlie’s BFF “Evil” Ed Thompson, and Toni Collete (The Sixth Sense) as Charley’s mom.

Fright Night gets rolling this summer in New Mexico. It will arrive in theaters on Oct. 7, 2011.

The original Fright Night made Clatto’s list of 15 Vampire Movies That Won’t Make You Gay.
