After ending his run in the Marvel Cinematic Universe, Robert Downey Jr is ready to make his return to the cinema with an iconic role.

The first trailer for Dolittle was released on Monday ahead of a January release, with the 54-year-old actor portraying the titular character of Doctor John Dolittle from the children’s book series by Hugh Lofting.

“We have no choice but to embark on this perilous journey,” Downey Jr says in the clip as he kicks off an adventure to save the young Queen of England, while a rendition of Louis Armstrong’s What a Wonderful World by Canadian band Reuben and the Dark plays in the background.

Apart from Downey Jr as the main actor and executive producer, the film also features the voices of Ralph Fiennes as a tiger, Avengers co-star Tom Holland as a dog, Rami Malek as a gorilla, Marion Cotillard as a fox, Octavia Spencer as a duck, and Emma Thompson as the parrot Polynesia.
