That is a fabulous coat. 

[X] Possibly a teensy ref to Lestat’s fur-lined cloak in TVL? Not fluffy enough to be wolf, but hopefully fake fur for the movie.

This is the image you referred to (it appears that he’s wearing the same coat with jacket underneath as in the screencap above):

I don’t know of any cemeteries that have multiple levels like that, what is that, stadium seating?, definitely not in NOLA (at least one of the cemeteries in NOLA is that crowded tho). There is a scene in one version of the script (thanks @thesaramonster!) that mentions a graveyard in Transylvania of course, when Claudia and Louis are on their own, searching for other vampires:

MONTAGE OF SKETCHES

A TRANSLYVANIAN VILLAGE, A GRAVEYARD.

RUINED CASTLE AFTER CASTLE, LOOKING INTO THE SKIES…

LOUIS
The quest for these Old World
vampires filled me with bitterness.
We searched village after village,
ruin after ruin and I was glad when
always we found nothing. For what
could the damned really have to say
to the damned?

^So I don’t think Neil Jordan tried to include the scene in the book where they find and kill a zombpire, but that production still might have been sort of a reference to it. 

But it’s especially sad that Louis still has that coat after Claudia’s been killed ;A; 

Can you imagine how painful it would have been, returning to the hotel room he shared with Claudia, all her clothes and accessories exactly as they were when she left it last? ;A;
