Jessica Chastain cried on command and showed off her sinister "Other Mommy" smile on "Jimmy Kimmel Live!," earning praise from the internet Thursday.
The Academy Award-winning actress taught the late-night host and his audience how she crafted the creepy smile for her upcoming horror film. She shared that the trick was to hold tension in her body while plastering on a fake smile.
Chastain shook slightly as she locked into the expression, dropping a single tear as she stared down the camera lens.
"You just spurted out that tear with no problem like that?" the late night host asked.
"I'm a trained actress, Jimmy," she replied.
