Pocket-Lint: James Davis blows things up for a living. That’s what he quips when explaining to Pocket-lint just what the title of Floor Manager of an SFX department is all about. Not all special effects involve pyrotechnics or stunt men hurling themselves from rooftops, but the other part of Davis’s job doesn’t sound too bad either - he builds and designs gadgets for the movies. We caught up with him, and some of his inventions as used in Rowan Atkinson’s spy comedy Johnny English Reborn, on London’s South Bank.
