At one point in “Dolittle” (2020), Robert Downey Jr.’s doctor must sail to a place that’s never been found. The film itself also ends up in no man’s land – too formulaic to be interesting yet too quirky to have broad appeal. There’s lots of CG animals voiced by Hollywood celebrities. A couple of kids coax zoo-bound Downey out of retirement. High seas hijinks ensue. Downey channels Johnny Depp and tops it with a delicious crypto-Scottish accent. Antonio Banderas plays some kind of pirate. He’s fascinating to look at and listen to but, like the film, doesn’t do anything particularly memorable.
