Nolan's films are often brain-twisting with abundant riddles and twisted stories. However, the director loves details so much that he even hides them in the titles.

1. Inception

‘Inception’ has ambiguity in its definition. It can mean ‘a starting point’ and be used as an opposite to ‘extraction’. It took 10 years for Nolan to write this screenplay.

2. Interstellar

Interstellar means located, taking place, or traveling among the stars especially of the Milky Way galaxy.

3. Tenet

A principle or belief, especially one of the main principles of a religion or philosophy.

4. The prestige

The prestige surely means reputation or influence arising from success. The movie’s title derives from the practice of stage illusions having three parts: the setup, the performance, and the prestige (effect).
