Doctor Dolittle is best known for being the only person who can understand animals. Literally. That’s because he can converse with them in a way that no other person on the planet can. While it may not be exactly the kind of film you would expect to see in a climate that is filled with superheroes, it is a family friendly bit that can work with the right people.

And Universal’s Dolittle starring Robert Downey Jr. could be just that kind of film, especially when it’s going to open the new year. The studio has released a new trailer which sees Downey Jr. as the titular character, who sounds an awful like Sherlock Holmes – and acts a little bit like him too – and who goes on an incredible journey where he will encounter animals that only he can talk to. Check out the trailer below.

Robert Downey Jr. is no stranger to starring in ensemble films. He’s done it for the better part of ten years with Marvel Studios. But his tenure with the superhero studio is coming to an end, and now that he will not have to put the Iron Man suit on anymore, he can look forward to working on other projects like The Voyage of Doctor Dolittle.

The actor has just revealed his co-stars for the film and the animals they will be voicing. There is a wide range of talent from Kumail Nanjiani (The Big Sick), Octavia Spencer (The Shape of Water), John Cena (Ferdinand), Tom Holland (Spider-Man: Homecoming), Ralph Fiennes (In Bruges), Emma Thompson (Beauty and the Beast), Marion Cotillard (The Dark Knight Rises), and so much more have joined the cast.
