Liv and Maddie: The Movie is an upcoming 2018 American live-action/animated musical comedy adventure film based on the Disney Channel original sitcom of the same name. Produced by Beck & Hart Productions, Oops Doughnuts Productions, It's a Laugh Productions, and Mandeville Films, and distributed by Walt Disney Studios Motion Pictures, the film is set to release in Spring 2018. The film is going to be directed by Andy Fickman, written by John Peaslee and Nicholas Stoller, and produced by David Hoberman and Todd Lieberman. The movie will be rated G, making it the first Disney film to ever receive that rating in a long time since Disney/Pixar's Monsters University. The movie is also the definitive series finale of Liv and Maddie.
The film takes place 2 days after the series finale episode of the Disney Channel sitcom, Liv and Maddie, in Malibu, California, where the two identical twin sisters, Liv and Maddie Rooney (both played by Dove Cameron), would be separated for awhile, because Liv would be going off to Paris for her world tour, and Maddie would be going to the Olympic basketball training camp with her ex-boyfriend, Diggie (Ryan McCartan).
While Liv is on tour in Paris, her voice withered away and was considered to be lost for good, but her manager, an evil hand-drawn animated cartoon microphone named Michael Carlphone Toonsmith (voiced by Alan Tudyk), won't let her cancel the tour, because he would lose all of his own money, so Maddie has to come to Paris, along with her new friends, a girly hand-drawn animated cartoon flower named Daisy Looney (voiced by Dove Cameron, the same actress that played Liv and Maddie) and her boyfriend, a handsome hand-drawn animated cartoon leaf named Leafard Tooney (voiced by Ross Lynch), to save the day and Liv.
In order to save Liv's life and her voice, Maddie has to pose as Liv on her tour, while Daisy and Leafard would go and take the real Liv to a hospital for vocal surgery. Everything is going fine, until Maddie (as Liv) is seen out with Diggie and the world thinks it's Liv and she's got a new boyfriend. Meanwhile, when Michael the Evil Microphone plans to kidnap Liv and use her as a power source for his world-destroying weapon, Maddie, Leafard, and Daisy need to stop him from trying to take over the entire world.

After Liv and Maddie has stopped airing on Disney Channel and it ended with the series finale episode "End-A-Rooney", Dove Cameron, the actress who played the two titular characters, Liv and Maddie Rooney, had come up with an idea of a feature-length movie based on the Disney Channel sitcom. Not only that, she also came up with the plot for the film all by herself.
While the script is in progress, Dove Cameron decided to not only reprise her role as Liv and Maddie Rooney, but she also signed on for a new role as the animated character Daisy Looney and get to portray and voice all of the Liv and Maddie robot clones.
The animation for the film will be made by Walt Disney Animation Studios, Yowza Animation, Toon City Animation, and Rough Draft Studios. Originally, the film was going to be a legitimately fully live-action film meaning it wouldn't include animated elements, but after Andy Fickman and Dove Cameron saw the test footage that was made by Mark Henn and Eric Goldberg, featuring hand-drawn animated versions of Liv and Maddie Rooney, the film would be a live-action/animated hybrid. Eric Goldberg will be the animation supervisor, while Mark Henn will be the lead animator and John Lasseter will be the animation director, creative consultant, and executive producer of the movie.
The visual effects and compositing for the film will be made by Digital Domain, Tippett Studio, Industrial Light & Magic, Blur Studio, Method Studios, and Framestore. Jim Henson's Creature Shop and Puppet Heap will provide live-action reference puppets for all of the animated characters from the movie.
The film was originally going to be released in October 2017, but was delayed to Spring 2018 due to the fact that animation for the film had started in April 2017.
