Moran scripted the 2005 film "Severance", which concerns office workers on a team building trip being stalked by a masked killer. Talking about where the idea for "Severance" came from, Moran said "I'd been trying to think of a good horror idea, and one day had a really bad commute home – yuppies in pinstripe suits were everywhere, pushing past me, jumping the queue, and generally being the ignorant scumbags that they are. So, in a flash of temper, I decided to kill off some yuppies in a horror – take them to a cabin, and pick them off one by one. Once I'd calmed down, I thought that was a pretty good idea – take some standard, British office types, and throw them into a cabin-in-the-woods horror, see how they react. And it developed from there."
