I Have a recent movie (in theatres) question!?

My mom thinks that there was a movie that came out recently (or maybe coming out soon) that has a man who is married who is looking for his wife to be open to an open marriage with him and another woman... she thought it included jeffrey dean morgan (denny from grey's anatomy) but i researched that and found nothing. does anyone know what movie I am talking about or did she just dream this up?
