Hasta La Motion!

I have a short film Im working on, and I have a scene that we have to film where our male lead walks through a open apartment and we really need the apartment to have moving boxes lining the walls.

We went over to uhaul today to pick some up because we had a ton of people that are apart of the production going to stores to pick them up, however most every store wouldnt give us any, or they would only give us a handful anyhow.

These moving boxes are like 12 a piece here in NYC 🙁

Someone suggest we just shoot the scene and then add the boxes in post…..

Does anyone have any ideas on best idea in achieving this? I am a fairly competent editor fcp or avid, and know keyframe/roto/basic composition and used to know a lil after effects during college (10 or so years ago, since then Ive always farmed it out to you professionals) lol. Im sure tons have changed, so basically trying to get a feel for if its possible and how?

Green screen it? My dp knows a good deal on green screen. My personal machine has photoshop/afx/shake/fcp…so Id prefer to try to use a program I have.

So any ideas, if so….how so? and ideas?

Thank you so much in advance
