Olivia Wilde to take lead in Chemistry

August 26th, 2011

Olivia Wilde is set to replace Jennifer Garner in 'Better Living Through Chemistry'.

The 'Cowboys and Aliens' actress is believed to be in negotiations to star in the dark comedic thriller, which had originally lined up her 'Butter' co-star before she recently became pregnant with her third child.

The movie tells the story of a prudish pharmacist - who will be played by Sam Rockwell - stuck in a love-less marriage, who starts having an affair with a female customer (Olivia) who takes him on a whirlwind ride of sex, drugs and possibly murder when they begin plotting to kill her husband.

Dame Judi Dench is in line to be the film's narrator and Michelle Monaghan will play Sam's onscreen wife.

Olivia may not have trouble filming her raunchy scenes with her 'Cowboys and Aliens' co-star after recently revealing her mother Leslie Cockburn, who is a producer on CBS news show '60 Minutes', taught her how to be sexy.

The 'Tron: Legacy' actress explained: "My mum taught me a lot. Especially about how, as a woman, you can be sexy and attractive and yet still be the smartest person in the room."
