The award winner for best short film at the 2007 US Comedy Arts Festival (now known simply as The Comedy Festival) was "My Wife Is Retarded," starring Gary Cole, Sean Astin, Leslie Bibb, Phyllis George and George Segal. It was written and directed by Etan Cohen, co-writer of "Tropic Thunder." Other than that, all I know about it is the IMDb plot description: "A man learns the secret behind his perfect marriage."
Are you offended yet? I can't say if I am, because I haven't seen the movie. If the premise is that an intellectually disabled woman is the ideal spouse, or that all women are intellectually disabled, well... I might find that deplorable, depending on how it's presented. Is the movie advocating that point of view? Is it "joking" the way R--- L------- used to about "feminazis," implying that a woman's place is in a coma? Is it the husband who wishes his wife was intellectually impaired? Does she feel like that's what her husband expects from her? There are so many conceptual approaches you could imagine for a movie of that title, some of which seem to offer comedic possibilities, and others that are maybe not-so-promising. But you never know until you actually see it. And, for some people, not even then.
