- It's artificial? - Of course it is.
Interestingly enough the line was shot as "Of course not" but changed to "Of course it is" in ADR. You can see her lip movements are saying "not". It's interesting that either way, the follow-up lines "Must be expensive? - Very." still make sense, but the implications are different: as seen in the film, Tyrell can afford a very expensive artificial owl, but in the original scripted line, they're saying Tyrell can even afford a *real* owl, which is much more significant in the film's world.
