I forgot to mention the other day while the scene of Barnabas and Willie disposing of Julia's body was current in the slideshow that I find it amusing that it's the only sequence in the film in which Barnabas wears his hat, gloves and sunglasses at night. Was he afraid of moonburn?
But seriously, I do actually have a theory as to why it may be that it's the only nighttime scene in the entire film with Barnabas dressed like that - and it's that perhaps the scene was mostly if not entirely shot second unit with stand-ins instead of with Johnny Depp and Jackie Earle Haley. The scene is almost exclusive comprised of long shots without any close ups of the characters - and the characters are nearly always seen in shadow. (The capture I'm sharing is the only time in the scene where Barnabas is even slightly seen in a bit of light as the beacon from a lighthouse passes by - but it only lasts on screen for an instant - and Willie's face is never really seen). And it seems fairly clear that the dialogue was looped for the sequence. So, if my theory is the case, dressing Barnabas up in that manner would have been a good way to disguise that it wasn't Depp shooting the scene.
