Monster Family (also known as Happy Family in Germany) is a 2017 animated monster comedy film directed by Holger Tappe, and written by David Safier and Catharina Junk, based on Safier's 2011 novel Happy Family. The film stars Emily Watson, Nick Frost, Jessica Brown Findlay, Celia Imrie, Catherine Tate, and Jason Isaacs.

The film received generally negative reviews from critics, and was a box-office bomb, grossing $27.8 million against a $30 million budget. A sequel titled Monster Family 2 was released in 2021.

In Transylvania, Count Dracula laments about his loneliness with his three bat servants. He receives a phone call from Emma Wishbone who has mistakenly called him instead of a monster costume store. She talks to him briefly before accidentally dropping her cell phone down a storm drain. Emma is depressed as family tensions build up - her own bookstore is in dire financial straits, her son Max is a victim of bullying due to his awkward and stereotypical mannerisms, her daughter Fay is a narcissistic teenager, and her husband Frank is overworked and sleep-deprived, neglecting her. Dracula decides to make Emma his new bride and persuades Baba Yaga to curse her and turn her into a real vampire so she will stay with him.

Her new-age friend Cheyenne gives Emma some tickets to a costume party, and Emma makes costumes for Emma's family: She as a vampire, Frank as Frankenstein's monster, Fay as a mummy, and Max as a werewolf. Due to a mix-up at the party, they are thrown out by security, causing Emma to have a breakdown. Baba Yaga takes advantage of the situation and curses her, but as her entire family were unhappy, they are all cursed and transform into the monsters they dressed up as.

Emma chases Baba Yaga who escapes, but not before they learn that her amulet needs to be recharged at the London Eye which happens to have been built on a site of ancient power. Meanwhile, Max scares his bully, enjoying his transformation and Fay is rejected by her school crush. Frank has lost his intelligence, but still shows love for Emma.

At the airport Fay hypnotizes a check-in clerk to allow them to fly, but during the flight Emma is overwhelmed by vampiric bloodlust, and only a timely intervention from Dracula halts this and he absconds with the confused and blood-hungry Emma aboard his personal jet leaving her family on the passenger plane.

Dracula tries to persuade Emma to stay with him, and although tempted she decides to be loyal to her family - causing Dracula to eject her from his plane where she lands next to the London Eye just as her family arrive. Meanwhile, Dracula decides that if he cannot have Emma, nobody can. He instructs his hunchback servant Renfield to prepare a snowflake machine to destroy the world in retaliation.

Baba Yaga charges her amulet but is accosted by the Wishbones, however she sends them to Egypt. Cheyenne tries to help, but after rescuing Baba Yaga from falling to her death the two become friends. Baba Yaga explains that Dracula intended for her to curse only Emma, but the entire family's unhappiness caused them all to change - only the entire family being happy will break the curse.
