(intended) Star Wars reference?
I don't recall for sure the name of Sultenfuss' undertaking partner who prepared the bodies in Sultenfuss' basement. Was it Arthur?
Anyway, when I saw the movie again recently I thought upon first glance, that might have been Keenan Ivory Wayans playing him because of the way he spoke Vadas' name ( I also did at first, actually think he resembled Keenan Wayans a wee bit; that is after I heard him say Vada) and the fact that he sounded, at least early in the movie, noticeably like Billy Dee Williams.
With the girl being named Vada, keeping in mind the subtly swaggering, care-free rhythm of Billy Williams' speech and "r"s specifically, whether it was intended or not, I thought that was a neat little, potentially 'inside' gag or reference to Star Wars.
