Response to a movie

https://youtu.be/AvSZt3cUECE 1) Looking at the Hitchcock adaptation of the Buchan novella, it's clear that symmetries are more important. Discuss them. 2) What, if you agree with this, makes the film superior to the novella? 3) How does Hitchcock generate suspense in the film? 4) Discuss a key theme in the film. If you choose your own topic, you are free to ignore the Buchan and focus only on the film.
