Now here is an interesting little movie connection. Lucio Fulci's Perversion Story (1969) makes use of San Quentin Prison for the gas chamber sequences. Now San Quentin 1969, hmmmmm...
To think that it may have been a been a worrying time for George Dumurrier but he may have got the chance to see Johnny Cash. Still, I suppose George had more pressing things on his mind at the time.
The posted video features footage from the prison and the song Walk The Line.
