Добрий день, Людмила,
Instead of using "Hollywood" movies, I would suggest looking at some other online video sites and also sites with multimedia specifically created for English langauge learners.
School Tube (Thousands of videos created and shared by students. Your students might really enjoy these!):
http://www.schooltube.com/
BBC "Free videos, recordings and quizzes to help you learn about and practise English pronunciation..."
LearnEnglish Central from the British Council
Voice of America - Learning American English (audio, text, and video)
I hope this helps you a little bit.
Будь здоровий!
Greg
