Vera Drake (2004)
- Discussions about the script and the characters. Each biography was designed since the birth of the character.
- Documentation about the period and the personalities. Actors read, watched and listened to period archives that their characters would have been exposed to e.g. books, newspapers, movies, TV programs, radio programs, etc.
- Improvisation of scenes that were afterwards used in the movie or not.
This mainly explains the "real life" feeling of the movie.
