The actress, who portrays a stay-at-home mother who believes she is turning into a dog, appeared to be miles away from red-carpet glamour with a billowing striped shirt and wide slacks.
She wasn’t wearing any makeup when she was seen filming sequences for the movie in Los Angeles on Tuesday.
The actress paired her ensemble with a pair of brown Birkenstocks as well.
She had to simulate a sequence in which she strikes Scoot McNairy across the face while it was being filmed.
