What actors and actresses appeared in Tribes - 1990?

There seems to be some confusion. "Tribes" is not a film from 1990. There are a few possibilities:

* "Tribes" is a play, not a movie. It was written by Nina Raine and premiered in 2010.

* You might be thinking of a different film. Can you provide more details about the film you're interested in, like the genre, director, or any specific plot points?

Please provide more information so I can help you find the cast of the film you're looking for.
