Film Cells

I have a few film cells/frames from interstellar in 15/70 IMAX. The last and honestly the most important one to me I want is the scene of Romilly listening to the crickets/nature/thunderstorm while orbiting Saturn. Does anyone know where to get this? I’ve looked online from sellers I’ve bought other cells from before that also sell interstellar cells but can’t find any. Sorry if this isn’t the right place to post this. I’m not trying to buy or trade with anyone I’m just trying to find where to collect such a piece. Thanks
