- New Bot Day! Old B.O.B. appeared in Disney’s The Black Hole (1979). BOB stands for BiO-sanitation Battalion. He’s old and cantankerous but tells the truth and is key to the story. Slim Pickens’ distinct voice perfectly establishes the character, as does the shabby design. I have great memories of this too-dark, unsettling, hard-to-recommend movie, but I love the bots!
