If you decide to exclude voice acting, Robin Williams’ last on-screen role was in the third installment of a very familiar film franchise: “Night at the Museum: Secret of the Tomb,” in which he played Teddy Roosevelt. (or at least Roosevelt’s New Duplicate from the York Museum of Natural History). He also voiced the legendary avian god Garuda for the production.
But, as noted earlier, Williams was almost more known for his voice acting than his live performances, so you might be surprised to learn that his IMDb page contains a final role in this medium that is a bit under the radar compared to a “Night at the Museum” movie. That film would be “Absolutely Anything,” a sci-fi/fantasy comedy directed by the late Terry Jones of Monty Python, starring Simon Pegg and Kate Beckinsale. The film features a variety of non-human characters, most of them voiced by all of the surviving members of the Monty Python Troupe, joined by Williams as “Dennis the Dog”.
The film was released in 2015 in the UK, but took another two years to release in the US, which could be one of the reasons why it doesn’t have as high a profile as expected. This is the very last cinematic performance of an incredible career.
