The film business is globalising in ways that not only Matt Damon will find confusing. Had I been there with him at The Great Wall première in February, I would have pointed out that Grauman’s Chinese Theatre isn’t actually called Grauman’s Chinese Theatre these days. It’s now officially the TCL Chinese Theatre, after the naming rights were sold to China’s TCL Corporation in 2013. Perhaps he’d have found it reassuring to know that, although he wasn’t in China any more, China was still there with him.
