Margot Kidder

Margaret Ruth Kidder (born October 17, 1948) is a Canadian-American actress, best known for playing Lois Lane in the Superman movies starring Christopher Reeve. Kidder has been diagnosed with bipolar disorder, which led to a widely publicized manic episode in 1996. Kidder was found in undergrowth by Los Angeles police in a distressed state, and placed in psychiatric care.

Kidder rampages while dining at the Griffin home in "Mr. Saturday Knight" and smashes the window to leave. After Jonathan Weed is pronounced dead, she comes back screaming, calmly explains she forgot her purse, then resumes her rampage.

Kidder is voiced by Rachael MacFarlane.
