When I was a kid my brothers and I used to watch those corny old black-and-white midday matinee movies on TV, and one of my favourites was an action adventure called “Boom Town”. It starred Clark Gable and Spencer Tracey as “Big John” Masters and “Square John” Sands, a couple of handsome wildcatters chancing their luck on the California oil fields. Together they carve out an empire in a rollicking western town where the saloons are overflowing with cowboys and dancing girls, and everyone is prospecting for something.
