So I was just checking out the Warner Shop, where you can purchase the Bluray and DVD version of the Director's Cut. What was interesting is that they list in the details tab that it has a running time of 88 minutes. However, when you check out the Digital Download version(Windows Media - Buy), it lists the running time as 86 minutes:
I contacted them to confirm that this is a typo, and that the digital version is the same Director's Cut. But how funny would that be if that wasn't the case, and it was indeed the original theatrical cut!
