When you start with movies, watching an English language movie with English subtitles is a good choice, but please bear in mind that sometimes the subtitles do not exactly match the language spoken in the movie. You can also download subtitles from the internet; look for the .srt file extension. Make sure you match the correct subtitles to the movie. I once unknowingly downloaded American subtitles for an Australian movie, where the language had been changed to suit the American audience. They did not match my Australian (original) version of the movie at all!
One thing I recommend is to first watch a movie you know well, so that you can follow the plot without getting frustrated if you can't understand every word. Then, watch a movie or TV series about a subject area you are interested in. For example, if you like building and architecture, try watching Grand Designs. If you like cars, try Top Gear.
Here is a list of my favourite movies which feature language learning and language barriers. I think most second-language learners can identify with some of the experiences the characters have in these movies. After watching your favourite blockbusters, try these:
1. My Fair Lady (1964)
An English classic - especially the pronunciation classes.
It is quite long and please remember that it is a musical!
2. The Terminal (2004)
I think most language learners can identify with some of the
communication problems the main character encounters.
3. The King's Speech (2010)
4. Green Card (1990)
For both teachers and learners, English Behind the Scenes has worksheets which go with movies. Personally I find them to be a little bit long-winded and I prefer to watch movies for pleasure, not for detailed language, comprehension, or analysis (particularly in a second language).
Happy viewing!
