New year, new reboot. Dr. Dolitte is back, but this time, it's just "Dolittle."

In the newest film adaptation, Dr. John Dolittle (Robert Downey Jr.) lives in solitude behind the high walls of his lush manor in 19th-century England. His only companionship comes from an array of exotic animals that he speaks to on a daily basis. But when young Queen Victoria (Jessie Buckley) becomes gravely ill, the eccentric doctor and his furry friends embark on an epic adventure to a mythical island to find the cure.

Actors Antonio Banderas, Michael Sheen, Harry Collett, Jim Broadbent also star in the film as well as Selena Gomez, Octavia Spencer, Emma Thompson, Rami Malek, John Cena, Kumail Nanjiani, Tom Holland, Craig Robinson, and Ralph Fiennes who lend their voices to some Dr. Dolittle's animal friends.
