The Courage of Others is the third studio album by American folk rock band Midlake.
It was released on February 1, 2010, on Bella Union Records.
The album sleeve pays homage to "Andrei Rublev", a 1966 film by Russian writer and director Andrei Tarkovsky. 
With a budget between $35,000, and $40,000 the film was shot on both super 8 and 16mm film.
Andrew Jordan figured that they would not get any publicity for the movie if the true budget was announced.
So he convinced Barry J. Gillis to go along with the lie that the movie was shot on $350,000 dollars.
It wasn't until recent years that Gillis and Jordan began revealing the true budget for the movie.
"Things" reputedly pays homage to several horror icons and films, such as George A. Romero and his feature film "Night Of The Living Dead", by having the film play on a television screen in the background while porn queen Amber Lynn talks about the case.
Romero fought in the courts to try and instate copyright on "Night Of The Living Dead", which had been put into the public domain on a technicality.
When one of the players in the movie finds an old tape recorder, clicks "play," and then weird chants and weird dialogue blast through the recorders speaker, the scene ostensibly evokes the 16mm feature film "The Evil Dead", while the original "Last House on the Left" is mentioned by name by one of the players.
