A number only seen in the movies?

Question

In the lyrics of a song I heard, it says:

'A quick glance over my shoulder reveals a number only seen in the movies, shards of glass and a decayed piece of parchment half buried"

Can anyone one help tell me what they mean in the lyrics by 'a number only seen in the movies'?
