I've noticed that the X-Files has 2 different opening credit sequences: one with those weird growing goo fern things and the text "Paranormal Activity" and one without. Does anyone know why?
The opening sequence stayed the same from Season 1 through Season 7 (Duchovny left). With Season 8, Robert Patrick was added, pictures of Mulder and Scully were updated and other images were altered. Season 9 saw a completely new opening sequence.
