This reminded me of a James Bond movie, which I love. The chase scenes and guns were unexpected, as well as that detective (who was he?). Production for this was completed in 4 months (what?!). Now I want to watch more animated crime films.
Here are some similarities and differences I saw vs more recent Miyazaki films:
Similarities:
1. Scenery camera pans
2. Delicious-looking food
3. Cool 1960s Italian cars
Differences:
1. Face structure (got more complex)
2. Detail
3. Music? (maybe)
