If you've been waiting patiently for the Season 3 premiere of Homeland, you're not alone – but there are certainly fewer Homeland fans who can say that now than a week ago. The third season of the series debuts later this month, but thanks to a leaked version of the premiere that appeared online yesterday, many fans have already gotten an early look at the return of Showtime's political paranoiafest.

The TorrentFreak blog was the first to report the leak, noting that the episode lacked opening credits, some visual effects and a final sound mix. "Since it is a workprint, the source of the leak is likely connected to a post-production studio," wrote Torrentfreak founder Ernesto in the blog post.

Variety had a different idea about where the leak originated, however, noting that the leaked episode "resembles the screener handed to critics at July's Television Critics Association event in Los Angeles," again noting the lack of credits and special effects, and observation seconded by NPR pop culture blogger Linda Holmes.

No matter where the leak came from, it was apparently a popular one: According to TorrentFreak, more than 100,000 people downloaded the episode within hours of it appearing online, although a BitTorrent spokesman told Deadline that true download numbers weren't actually available to anyone other than the original uploader.

Showtime did not respond to a request for comment by the time of publication. The Season 3 premiere of Showtime will air on Sept. 29 at 9 p.m.
