Didn't they make film at Harrow as well at one time in the not-so-distant past? It was my understanding that they did. In my freezer are several boxes of Portra 160VC that clearly say "Made in Great Britain." The Pension Plan might do very well to explore bringing back that capability once things are up and running.
Personally, I am more comfortable with a UK based operation rationally looking at the business case of film production at Harrow (or elsewhere outside of Rochester) and developing a business plan to move forward.* UK businesses seem to far more comfortable taking sensible risks** and making the necessary investments to pull off the plan than US companies and their Wall Street mandated profit non-sense. That's been my experience anyway.
* Maybe they'd even consider specialty product runs, not unlike Ilford's ULF runs. Maybe we could see E6 products again (or maybe even Koda... Nah, I ain't going there! )
**as opposed to stupid risks, so I'm talking about things that could reasonably be expected to pan out
