Sometimes our station that airs Jeopardy puts on old episodes in the early hours of the morning on the weekends. I thought they were probably several years old, but this one turned out to be from 2012. Since the movie came out then, it's interesting that they ignored that part. Maybe it was from early in the year.
Anyway, the "answer" was:
"Before 'Twilight' and 'Buffy the Vampire Slayer,' there was this Gothic series and its 1991 remake about Barnabas Collins.
