Jennifer Garner in a chemistry thriller

ValentinesDay star Jennifer Garner is all set to star alongside Jeremy Renner in a new thriller Better Living Through Chemistry.

The actress, who is married to Ben Affleck, is in talks to star opposite Renner to play a trophy wife in the movie, which will see writers Geoff Moore and David Posamentier make their directorial debut.

To be made by Occupant Films, the movie tells the story of a small-town pharmacist, played by Renner, who is stuck in a loveless marriage and rediscovers himself by having an affair with Garner's married alter-ego.

She introduces him to the pleasures of prescription drugs but things take a turn for the worse when the romance escalates and they start plotting to kill Garner's husband, the Hollywood Reporter said.

Although she is talks to star in this movie, Jennifer has previously admitted she was considering returning to TV work as it is much more stable than making movies.

The mother-of-two, who starred in sci-fi drama Alias said, "I never say never to TV because it has been really good for me. I am not a snob about work. The great thing about TV is you can stay in one place. Eventually my kids aren't going to want to be living all over the place. Television would allow us to settle down."
