House actress Lisa Edelstein has moved into the political arena as she takes on the G.O.P. in a new ‘right to choose’ ad made in conjunction with activist group MoveOn.org.

The 43-year-old, who plays Dr. House’s love interest, Dr Lisa Cuddy on the Emmy award winning drama, stars in a new 30-second TV ad as a woman who is forced into a “back alley” to undergo a pregnancy termination.

The message is a direct attack on what MoveOn.org claim is the Republican party’s assault on women’s health and their right to choose.

The ad opens with Edelstein dressed in 1950s-era clothing walking shakily down a hallway towards a door as you hear her voice saying: “Decades ago, women suffered through horrifying back alley abortions. Or, they used dangerous methods when they had no other recourse.”

And it ends with a terrified Edelstein, dressed in modern day clothing, tearfully opening a closet door to reveal a wire clothes hanger, a scene symbolically associated with the dangerous situations women were forced into before they gained reproductive rights.

Edelstein’s voice then asks: “Why is the G.O.P. trying to send women back to the back alley?”

The actress, who is an outspoken advocate for women’s rights, as well as a volunteer for the Best Friends Animal Society, Save the Children and Planned Parenthood, explained her decision to star in the ad: “I decided to do this ad because I believe that every woman needs to know the grave danger that women’s reproductive rights are facing in Congress right now,” she said.

I hope that women across America tell Congress that these bills are an attack on women’s health and that they are unacceptable.”

“

This ad is a wakeup call,” said Kat Barr, Campaign Director at MoveOn.org.  “If Republican proposals go through, women could once again face fear and danger when it comes to their reproductive health.
