A Hollywood Christmas (2022) on Netflix

Plot summary

Jessica makes her living directing Christmas movies in Hollywood, and her newest one is already in production. Christopher, a network executive, arrives at the set intending to stop it, and she treats him as an opponent. Her assistant Reena points out the irony of the situation: Jessica is not just trying to rescue a Christmas movie, she is inside one. She has to manage the familiar ingredients of the genre, among them cast members whose romances flare up and cool off, a dog dressed as an elf that keeps wandering away, and her own attraction to the man she considers her rival.
