I watched this movie recently, which is about a Pakistani immigrant living in Chicago who falls in love with a white woman. I was struck by the similarities to the JW culture when the main character experiences trials with his traditional Muslim family. Essentially, he is shunned and his parents refuse to talk to him. It might make for an interesting conversation with a JW, and possibly assist them to start questioning their own faith. You never know what small things can trigger a person to start thinking!

Overall, it was an entertaining movie and I highly recommend it. It's available to stream for free on Amazon Prime (in the U.S anyway).
