Considering that Paranormal Activity cost only $15,000 produce and it has already grossed nearly $63 million, it should come as no surprise that the topic of a sequel has come up.

Paramount Chairman Brad Grey says that the studio owns the rights to a second installment and they'll do it if it makes sense.

Without diving into spoiler territory, PA's ending is certainly open-ended and a sequel could easily be worked out.

PA pulled a huge upset this past weekend by stealing the attention of horror fans away from Saw VI. PA will have to face off against another paranormal thriller when Universal's The Fourth Kind opens on November 6.
