Movies and ESL teaching

[Nannou]

One of my students today asked: "Madam, can I tell you something?"
I said "Its okay, go on please."
He answered: "I'm afraid it's not related to the lesson's topic."
I said "It doesn't matter. What do you want to say?"
He said: "Will you watch the film TWILIGHT on mbc MAX (an Arabic English-speaking Channel)tomorrow night.
I said: "Yes I'll watch it. It's good that you reminded me of it."
The other students said with excitement: "Yes Madam, It's a new and interesting film."
I said: "That's very good. So when you sit to watch it remember that I'm also sitting to watch it with you."
They were very delighted and answered in one voice; "Yes Madam! Yes! We'll watch it with you."
The first student added: "I'm addicted to such movies which are broadcasted every Wednesday night."
I said: "That's very good for all of you to improve your English."

I was very impressed by my students' enthusiasm to watch such movies and wondered whether I can use them in such an ESL learning / teaching environment.
Thus, I'll be very grateful and thankful if you can give me any tips on how I can use these movies. Moreover, could you suggest any movie title which will be suitable to be used within this frame?

Thanks in advance

May I ask how old are your students?
