I have never actually seen the original 1967 Dr. Dolittle, starring Rex Harrison as the eponymous zoolingualist, but I vaguely recall both reading the 1920 children’s book The Story of Doctor Dolittle and seeing the 1998 Eddie Murphy film, so I suppose I am an expert. With that in mind, I am not entirely sure the world needs this action-adventure Dolittle remake starring Robert Downey, Jr. and a bunch of CGI animals, but I guess we’re getting it.
