I read that Robert Picardo (The Doctor) had auditioned for the part of Neelix. I think he could have played that role. Though Ethan brings a comedic spark to Neelix from his work on Benson. Who do you think of the existing cast could have played another character to their own?? Tim Russ (Tuvok) as The Doctor. Jennifer Lien (Kes) as Harriet Kim. Robert Beltran (Chakotay) as Chief Engineer Torres. Ethan Phillips.. Tuvok
