Laurie Metcalf as Mary Cooper
Metcalf plays Mary Cooper, Sheldon’s mother, who is a devout born-again Christian from East Texas. Her character has been a good contradiction to Sheldon’s strong persona.

The 62-year old actress who considers herself as a workaholic has numerous accolades and nominations to her name.
