Quick Scoop: Amanda Seyfried’s Age in Mamma Mia!

  • Amanda Seyfried’s date of birth: December 3, 1985.
  • Mamma Mia! was released in cinemas in 2008, placing her at 22 years old during filming and release.
  • She plays Sophie Sheridan, a twenty-something bride-to-be whose age and life stage line up closely with Seyfried’s real age at the time.
