Reba McEntire and Rachel Brosnahan are joining the voice cast of Fox animation's Spies in Disguise.

Will Smith will lead the cast as Lance Sterling, the world’s most awesome spy. Cool, charming and super-skilled, Sterling's occupation is saving the world. Tom Holland will play Walter, a great mind but perhaps not a great socializer. What he lacks in social skills, though, he makes up for in smarts and invention: Walter is the scientific genius who invents the gadgets Lance uses on his missions. When events take an unexpected turn, Walter and Lance suddenly have to rely on each other to work as a team, with the whole world in peril.

McEntire and Brosnahan will join a previously announced cast of Ben Mendelsohn, Karen Gillan, Rashida Jones, DJ Khaled and Masi Oka.

The project, based on an original animated short, Pigeon: Impossible, is directed by Nick Bruno & Troy Quane and comes from Blue Sky and Chernin Entertainment. Mark Ronson serves as executive music producer for the film.

McEntire, whose music career has earned the country superstar 16 ACM awards, 15 American music awards and three Grammys, is a 2018 recipient of the Kennedy Center Honor. She is repped by WME and Jackoway Austen.

The Emmy and Golden Globe-winning Brosnahan is set for the third season of Amazon's The Marvelous Mrs. Maisel and will star opposite Benedict Cumberbatch in the FilmNation drama Ironbank. She is repped by CAA, Brillstein Partners and Schreck Rose.

Spies in Disguise will hit theaters on Dec. 25, 2019.
