There may be one perfect song to end all movies - and Peter Salomone thinks he's found it.

He tested the theory that Dire Straits' 1985 hit Walk of Life wraps up any finale seemlessly.

He's tested the concept on titles across all genres, from The Matrix to Truman Show, The Lion King and even classics such as Casablanca and horror The Shining.

Salomone simply titled his findings The Walk of Life Project, and posted them on a special WOL YouTube channel.

An "announcement" video, also featuring the song, explains how it works in a few simple words: "50 movies, 1 song".

When the synthesizer organ kicks in, it sheds new light on scenes you may have witnessed a thousand times before.

Here are five of the best and most diverse offerings.

1. The Blair Witch Project

2. Casablanca

3. Terminator 2

4. The Graduate

5. Spider Man 2002
