It didn't even dawn on me to check to see if Liz' quote came from a different scene that the calendar hasn't gotten to yet. And really it should have because using quotes from entirely wrong eps was one of the major problems with the 1990 Calendar Of Quotes from the daytime show. But I just checked the costume party scenes, and Liz only has one line in the script, and it's not the one on the Movie Calendar for 1/31. (It's part of Scene #107A, a 3/11/70 rewrite, in reply to Barnabas thanking her for the party.) And, interestingly, the scene doesn't even appear in the novelization. In fact, the only reference to Liz at the costume party at all is a mention of her in the background talking to Stokes while Carolyn is looking for Barnabas. Odd...
As for today's quote, what a surprise, it differs from what's on the calendar: Barnabas: 'I am Barnabas Collins. May I come in?" And that quote also doesn't appear in the novelization - the novel has the same quote that's in DC's script, which is what is delivered in the film, and what I've used for the slideshow.
