Well, to make a long story short, Amanda Peet is Jewish!
Since Amanda Peet's mother is Jewish, and in Orthodox Judaism and Conservative Judaism, those with a Jewish mother (or those who underwent a halakhic conversion) are considered Jewish, then that makes her Jewish. Her father is not Jewish.
Amanda Peet was born on January 11, 1972 in New York City, New York, U.S..
She is known for such movies as Identity (2003), Something's Gotta Give (2003), Syriana (2005), The X Files: I Want to Believe (2008), 2012 (2009), The Way Way Back (2013) and Identity Thief (2013).
She has also appeared in the 1999 drama series Jack & Jill, the 2006 drama series Studio 60 on the Sunset Strip, and the 2015 comedy-drama series Togetherness.
