The Night Stalker script "The M Word" was heavily rewritten and became "Mulder and Scully Meet the Were-Monster" (10.03).

ENTERTAINMENT WEEKLY: When did you have the idea for “Mulder and Scully Meet the Were-Monster”? Did you always envision it as an X-Files story?
DARIN MORGAN: The basic story idea was one I came up with over a decade ago, working on another show. We didn’t get to do it. I’ve always wanted to, ‘cause I’ve always loved the basic story. But there’s not many shows that would allow you to do a Werelizard. [laughs]
Was that from your time working on The Night Stalker?
Yeah, that was The Night Stalker. Which was a crazy experience. I don’t know if you know the backstory. Frank Spotnitz, who was an old X-Files guy, was running it. And we were told, the first day, that even though we were doing a remake of The Night Stalker, we weren’t allowed to do stories about monsters. Or even use the word “monster.” And we just couldn’t believe it, ‘cause that didn’t make any sense. Why you would do a remake of a show about a man searching for monsters, and then not be able to use any monsters?
So I came up with the idea that: “Well, if this idea could work, that maybe this could prove to the network to let us do monster episodes.” We never got that far, ‘cause the show was canceled. But the idea always stayed with me. Of course, the [original] Night Stalker has so many similarities to the X-Files. It was a huge inspiration.
