What actors and actresses appeared in Somer - 1975?

There seems to be a misunderstanding. There is no known film or TV show titled "Somer - 1975." Could you be thinking of a different title or year?

Perhaps you could provide more context or details about the project you're interested in, such as the genre, plot, or any other actors involved. This would help me identify the correct title and provide the information you're looking for.
