Term for faking something in a movie related to set or lighting?

Question

So, I was under the incorrect assumption that the term "gaffe" referred to creating something that just looks close enough to pass on screen. I'm certain I heard this term used for barnum and bailey's "mermaid" creation. Now I want to know what the correct term for this is... I understand that this is technically what you would call special effects. but I'm looking more for the term when it is not a custom made "prop" but a slopped together prop that only looks good when not closely scrutinized.

Answer 1

Replica is the term used for creating a fake prop, however if you are creating low level detail replica prop then I guess it would be just scabbed together perhaps. I am sure the term varies from technical managing and developing. However, as long as your production team understands the language then I would say "The show must go on". I hope this helps?
