A couple of years ago, I saw an outstanding mini-documentary on YouTube. It relayed some trivia/behind the scenes stuff I already knew, but a lot of new stuff I'd never heard before.

I've searched for the doc but can't find it now. It had interviews with screenwriters Jeb Stuart and Steven E. de Souza as well as with director John McTiernan, so it was well-sourced.

Below, a list of ten cool things about Die Hard, many of which come from this documentary I cannot link for you.

1. Die Hard is a sequel, in a way, to the Frank Sinatra movie The Detective.

The Detective was based on the novel by Roderick Thorp (a name you might recognize). In that movie, Frank Sinatra played Joe Leland, a NYC detective.

Roderick Thorp went on to write a sequel called Nothing Lasts Forever, again featuring Joe Leland. That sequel involved terrorists taking over an office building, with Leland caught in the crossfire.
