Gorgeous “Hollyoaks” star Tiffany Mulheron is joining hot up-and-comers Sara Paxton (Last House On the Left, Shark Night 3-D) and Gillian Zinser (Manson Girls, “90210”) in writer/director Brian Brightly’s feature film debut Liars All (previously entitled Truth or Dare).

Set in London on New Year’s Eve, Liars All centers on a game of truth-or-dare that spins out of control for a group of friends. The Indie Entertainment and Sundial Pictures production is set to roll camera on Monday in Los Angeles.

Mulheron’s genre creds include the rock-and-roll nightmare Dark Journey and the horror-comedy Lesbian Vampire Killers. She is best known, however, for her role as mean-bitch Natalie Osborne on the outrageously sexy British soap “Hollyoaks.”

Liars All costars Matt Lanter (The Roommate), Torrance Combs (“The Tudors”), Randy Wayne (Grizzly Park), and Alice Evans, who played a young Eloise Hawking on ABC’s “LOST.”
