Several possible endings will be filmed for the final ever episode of The Office.

Mackenzie Crook, who plays Gareth in the hit BBC comedy series, has revealed that creators Ricky Gervais and Stephen Merchant have come up with "numerous" possible endings for the last episode, which will air this Christmas.

"I'm told Ricky Gervais has been writing numerous endings so no one knows what's going to happen to Slough's favourite stationery business," he said.

"Who knows what they will cook up? I wouldn't put anything past Ricky. Perhaps there will be a Who Shot JR thing with David Brent.

"I'd like Gareth to blow the place up and take everyone out. But I guess we'll all have to wait and see."
