I was watching Jeepers Creepers last night, and then the cast interviews on the DVD. Eileen Brennan (who plays the crazy old lady who lives in a remote house with dozens of cats) was talking about her character, and remarked that she also has several cats in real life.
By way of justification, she pointed out:
They're comforting. Like a big potato.
Perhaps she’s also completely off her head in real life.
