Anne's "neighbor from hell" Francine's house number is 666.

When Annie is listing Academy Award winners for Best Picture at the auditions for the Quiz Show, she ends with CODA (2021), a film about the only hearing person in a deaf family. When the camera pans to the audience, you can clearly see someone applaud like a deaf person by waving their hands in the air.
