Kate & Alaina

Kate & Alaina is a 2018 American computer-animated science fiction comedy crossover direct-to-video film produced by Thalia Ward Productions and Fox Animation Studios as their first collaborative project, and it is also Fox Animation's first direct-to-video film since 1999's Bartok the Magnificent. As the first official Kate & Chris/Alaina Gleen crossover film, it was directed by Mark Simon and Jason Plapp and written by Brad Copeland.

The idea for a crossover film was suggested by Fox Animation's co-president Robert Baird, and the film was announced by 20th Century Fox in October 2017. Although both Fox Animation and Thalia Ward worked on this collaboration, most of the production was handled by Fox Animation. It was released on DVD, Blu-ray and digital media on December 18, 2018 by 20th Century Fox Home Entertainment, and was met with received mixed reviews from critics.
