First four episodes of fifth season of the series are leaked online, a day before the HBO premiere. Leaked versions appear to have been copied from DVDs given to members of the press in advance of their broadcast on HBO. Producer Greg Spence:
The cast is looping all over the world, sending files back and forth. Artists are working in special-effects houses all over the world. The files are watermarked, and editors have to confirm in writing that they’ve deleted them.
