A 12-minute film in which Erlang's creators demonstrate the language's fault tolerance and live-system features, including phoning each other to show it working. This version has fixed audio.
HN recommends it as a charming, concise demonstration of what makes Erlang special, from the people who built it.

This is almost certainly a reference to Erlang: The Movie [1] which is the most glorious 11 minutes of some programmers explaining how their creation works you will ever see. In the video, the three call each other to demonstrate what happens real-time in an Erlang system. For the impatient, the telephone conversation starts at about minute 3. [1]: this video
Fred probably forgot to mention it, but Joe, Mike, and Robert starred in a short film Erlang: The Movie , a very fine and concise demonstration of fault-tolerance of Erlang. The film has some magic power that I cannot describe but made me watching it over and over again. YouTube link to the film with fixed audio: this video
Interestingly, if you watch the Erlang: The Movie ( this video ) they use the term 'declarative programming' to refer to what we would now call 'functional programming'. It's an interesting way of thinking about it - these sort of declarative interfaces are very simple in languages with first class function support.
This is the same "movie", but the audio has been fixed to not play out of just the left ear: this video
