American actress Miriam Shor was born on July 25, 1971 in Minneapolis, Minnesota. She spent her childhood moving back and forth between Detroit, Michigan and Turin, Italy, since her mother and father have divorced. She eventually settled down in 1989, and she entered Ferndale High School. She studied at the University of Michigan, where she began appearing in school productions.
She began acting for the screen in 1999, appearing in the dramatic film Entropy. She spent most of her early career appearing as a guest on television shows such as Becker, Then Came You, Married to the Kellys, The West Wing and My Name is Earl. She also appeared in films such as Bedazzled, Set Set Spike, Pizza and Shortbus.
In 2006, Shor got her first regular television role, appearing in the romantic comedy Big Day. Her character, Becca, tried to get Skobo (Stephen Rannazzisi) banned from wedding. The series was a ratings disappointment, and the network cancelled it after 12 episodes, leaving one more unaired. Unfazed, Shor signed on for another regular television role, this time for the controversial period drama Swingtown. There, she played the role of Janet Thompson.
