Despite the sub-zero temperatures in Scotland, the team behind Citadel has started shooting in Glasgow.

The Irish-UK co-production stars Aneurin Barnard (Ironclad), James Cosmo (Braveheart) and Wunmi Mosuka (I Am Slave). Co-stars are Ingrid Craigie and Amy Shiels.

Katie Holly of Blinder Films and Brian Coffey of Sigma Films produce. Executive producers are Kieron J. Walsh, Gillian Berrie and David Mackenzie.

Ciaran Foy, an NFTS graduate, writes and directs his debut feature.

The story is about feral children who attack in a council estate. One father has to fight the gangs with the help of a priest.

THe project is shooting for three weeks on location and in a Glasgow studio and one week in Dublin. The film is being readied for an autumn 2011 release.

Backing comes from The Irish Film Board, Creative Scotland, Section 481 and the UK Tax Credit.

Producers Holly and Coffey said in a statement:

“In these truly Siberian conditions we’ve had to face all kinds of issues – cancelled flights,

impassable roads, freezing

conditions – a snow plough was even drafted in to preserve this

already ambitious schedule. It’s ironic given that we’re shooting a film where the central

character is afflicted with agoraphobia that we have to spend so much time out of doors!

We’re just thrilled that we have such an amazingly resilient, adaptable and committed cast

and crew who are battling the elements to get us through and we are literally ploughing on

despite everything that has been thrown at us. Spirits are high, the performances are

amazing, the material fantastic and Citadel’s off to Dublin come wind, hail or snow.”
