What actors and actresses appeared in Tristan und Isolde - 1996?

"Tristan und Isolde" is an opera by Richard Wagner, not a film. Therefore, there are no actors or actresses in the sense of a film cast.

The 1996 production you are referring to likely refers to a specific performance of the opera. To determine the cast of that particular performance, you would need to specify:

* The opera house or company: Was it a Metropolitan Opera production? A Bayreuth Festival performance?

* The date: The cast changes with every performance.

Once you provide these details, I can help you find the cast list for the 1996 production of "Tristan und Isolde" you are interested in.
