Orlando - Concentrate on the key person, Javier Bardem, and show how protean an actor he is (your English teacher will be impressed by your use of that word). Do you think he is equally able to play a psycho serial killer in "No Country for Old Men" and a lovesick hangdog in "Love in the Time of Cholera?" Why do you suppose so many women fall for him when David Denby of New Yorker magazine says that he acts like the kind of guy that women would sooner give chicken soup to than make love to?
English teachers LOVE papers that compare and contrast, so make sure you see "No Country for Old Men" as well as "Cholera," and also try to see Bardem in "Mar Adento," which won the 2005 Oscar for best foreign language film about a paralyzed man who fought a 30-year campaign for euthanasia.
