The legendary actress debuted on the HBO show as Mary Louise Wright, who is the mother of Perry Wright (who was played by Alexander Skarsgård, until the character died in the season one finale).
Perry was married to Celeste Wright (played by Nicole Kidman) and Mary Louise is in town following her son's death.
The scream comes at the dinner table, where Streep is showing her grandsons how she dealt with her son's death. She told them she just wanted to scream ... and scream she did.
We’re definitely here for season 2.
