During the scene in which joe shoots ed in his office, his bloody hair points to the right of the frame, towards the Pizza poster, at first, the poster (the pizza) doesn't have any blood stains on it, but when joe comes back, a remarkable blood stain appear on the pizza.
this is a huge continuity error, so big i can only assume it's there for us to notice. the director goes a long way to point out to us (the viewers) to look on the pizza and notice the continuity error (kinda like kubrick), when joe goes to the room next door, where he accidentally shot a lady, there is a pizza dominos and number written on the chalkboard (to the left of the frame),
also, joe's strangling grip on her changes between scene cuts, the vacuum cleaner guy is moving as he if he is still alive when joe puts him on the floor next to the lady. the vacuum itself, apparently, has an endless electric chord.
these are big continuity errors that are bluntly shown to us.
is it to hint the viewers that this scene is a dream? assuming that the whole first couple of hours of the film are dream sequences, this is overstating it.
the continuity editing of the scene in ed's office is as messed up as joe's performance as a hitman, he winds up shooting three people making a lot of noise and leaving a lot of trace.
the director wants us to understand there is an italian theme in ed's office, the red carpet with the green and white file cabinets on the left of the frame ressemble the italian flag, along with the pizza poster and the fact that this scene is an "italian hit" style scene.
the Castigliane brothers are italian, are they connected to ed's misfortune in any way? ("this is no longer your film"). on the cabinet that joe is leaning on has a sticker with "Castigliane" printed on it, and the scene starts when ed is seemingly telling joe about the accident in mulholland drive in a funny angle.
"The Castiglioni Brothers" is a 1937 Italian comedy film according to wikipedia, couldn't find much details about the plot besides that it about italian cinema stardom vs talents.
"real Italian Pizza" is a 12 min experimental ethnographic film by David Rimmer from the early 70's,
apparently this movie shows cuts from the same unmoving camera, looking from above over a pizza stand, as if looking from a house window above and voyeuring the people and occurrences surrounding the pizza stand.
here's a review on it -
“Taken between September 1970 and May 1971, with the unmoving camera apparently bolted to the window ledge, this film, a ten-minute eternity, chronicles what takes place within view of the lens. The backdrop is a typical New York pizza stand, the actors are selected New Yorkers who happened to be there during the half year, the plot is the somewhat sinister aimlessness of life itself.” – Donald Ritchie, Museum of Modern Art, NY.
ed's office has a big window with a telescope on a tripod, this represents the unmoving camera looking down the street. the stove and pizza represent the pizza stand. it is as if ed is david rimmer shooting the film. the room next to his office, the one with the hurt lady is full off boxes, food cans, and a lot of junk (including a national geographic issue), the place looks like a props/setting room of a film production. combine that with the pizza and stove, Real Italian Pizza is blantly referenced in this scene.
