What actors and actresses appeared in Un obus sur Paris - 1913?

It seems you're asking about the film "Un obus sur Paris" (1913). However, it's difficult to give you a definite list of actors and actresses. Here's why:

* Early Silent Film: Films made in 1913 were silent films. Information about the actors and actresses involved was not often recorded systematically as it is today.

* Lost Film: This particular film, "Un obus sur Paris" (1913), is considered lost. This means no surviving copies of the film exist, making it impossible to identify the actors and actresses from the footage itself.

However, some information may exist in historical records:

* Film Archives: It's possible that some film archives or historical societies may have some documentation mentioning the cast members.

* Film Industry Publications: Contemporary trade publications from 1913 might have listed the actors.

It would be a research project to try and find this information.

I hope this explanation is helpful!
