All the slots for extras for an upcoming audio from Big Finish are now full. "Thanks to everyone who answered I thought I might get 10 replies," producer Gary Russell told Outpost Gallifrey. "Ten times that by Sunday and they're still coming... As I only needed about 25, I'm now closing this request cos I've got what I needed. But a very, very heartfelt thanks to everyone who responded. We at Big Finish Towers are enormously grateful, and flattered, that so many volunteered. Next time I'll hire a cathedral rather than a studio and we might fit everyone in."
