There's a film getting a theatrical run that caught my eye. "Tragedy of a Mother and Son" was written and directed by Romane Simon. I found this information about it at melodika.net...
According to Romane Simon, a multi-talented individual who is now living his dream to be part of show business, "Tragedy" deals with what has here-to-fore been a subject rarely approached in films, that of incest, although it occurs unintentionally by the film characters. However, Romane quickly adds, "While incest is explored in 'Tragedy,' the film really centers on one of the major problems of the 21st Century, the growing numbers of young adults who are not qualified to be parents.
From the information I found, I have no idea if "unintentional" is referring to a Genetic Sexual Attraction situation or something else, nor did I find any indication about whether the characters involved are mother and son or other characters. If anyone knows more, please comment.
Here's a trailer. You can tell that this is not a motion picture that had a large budget, but that doesn't mean it couldn't be an interesting production.
Here's a Facebook page and the IMDb page.
