Gant's Rule

Example of Gant's rule:

Into the Woods (Rob Marshall, 2014)
$50m budget, global box office by end January 2015: $165m. US box office: $125m. UK box office: £7.3m. 
IMDB; the-Numbers; BoxOfficeMojo; Wiki; Charles Gant's UK column late January 2015; Ben Child's US box office analysis;

There is a greater multiple than x10 when comparing US and UK box office, but the general point of the vastly larger scale can be seen. There may seem a bit of a mystery then as to why there is less than x10 the screens, but this reflects the much higher ticket prices typically charged in the US (2800 screens v 500). The film is unusual in one regard though: around 75% of the global take is from the USA alone; this has been typically around 50%, but recently has been declining to nearer 40% as China's cinema industry in particular grows in scale.
