What actors and actresses appeared in La Tosca - 1909?

You're asking about a tricky one! There's no film called "La Tosca - 1909." You are probably thinking of Puccini's opera, "La Tosca," which premiered in 1900.

Opera productions don't have a fixed cast like a film. The roles are filled by different singers each time the opera is performed. To find out who starred in a specific performance, you'd need to know the date, location, and company that staged the production.

If you can provide more information, I may be able to help you find out who was in the cast.
