Southern England - "It's Oscar-winning stuff of the highest quality," Major General Sir Monty Dambusta has told delighted MoD bosses at a progress meeting.
"We've even got that 'Borat' actor chappie who plays Hamid Karzai for some cameo shots in the George Cross scene."
The briefing has delighted Ministry big wigs who have heard how Harry's been holed up in a South Coast bunker making a vid upping his ginger nut profile to war hero status.
Modelled largely on the Pentagon's Area 51/Roswell film studios where the Apollo Moon Landing were hoaxed the subterranean complex forms part of the MoD's asymmetrical conflict strategy.
And it's churning out heart-warming footage as commissioned to order by the Palace.
"At 10 million squid the project's a bargain," Dambusta added, "and a lot more cost-effective than pitching Harry into Afghanistan along with his full Royal Protection Racket security detail as bait for pot-shots by warring Taleban."
Over 100 studio professionals are said to be in on the act including veteran Beeb heavyweights overseeing the project.
Head of landscaping consultation Sir David Rottenbra is in charge of visuals like Camp Bastion mock-ups and faux battle scenes.
He's working closely with Rolf Harris, Terry Wogan and Dr Jonathan Miller on 'Officer and a Gentleman' details with additional editorial input from the Beeb's Strictly Come Dancing panel.
Some nifty moves will see Harry immortalised in full gladiatorial glory smashing Taleban war lords and securing everlasting peace.
Darcey Bussell's tutu is not part of the deal.
