The rollercoaster that Grace and Jack ride was the original Colossus at Six Flags Magic Mountain. Opened in 1978, it lasted in its near-original form until closing in 2014. The 36-year old wooden roller coaster was then upgraded and reconfigured as the metal-and-wood Twisted Colossus, which opened in 2015.
The title refers to businessman, tycoon, philanthropist and oilman Armand Hammer who partially owned Occidental Petroleum.
