It Runs in the Family

You have probably seen the previews for the new movie It Runs in the Family.

The publicity highlights the movie’s two stars, son and father Michael and Kirk Douglas:

What is left unmentioned is that there are actually four members of the Douglas family the film: the other two are Michael’s son Cameron and Michael’s mother (and Kirk’s ex-wife) Diana (highlights are mine):

I assume that some sort of complicated Hollywood rules prevent the mention of these other Douglas family members without mentioning the other non-Douglas cast. But I gotta say, the promotion would be far more effective if it highlighted this “art imitating life” aspect of the picture.
