Bend it like Beckham

Well I guess the whole movie itself is funny, may be you can try encouraging them to think about the cultural differences the movie is trying to bring about and see if the students can relate it to the difference between Easten and Western cultures... may be how the culture in HK is a mixture,.. I believe relating the movie to the student's daily life would be most interesting =)

Hope it helps!
