Here’s video of Ricky Gervais appearing on The Office as David Brent (the original Michael Scott on the British version of The Office).
One thing that was interesting was that, with a wink and a nudge, they brought up the fact that Steve Carell is leaving. Brent asked if there was any openings at Dunder Mifflin and Scott said no. Brent then asked Scott to keep him posted if there are any openings.
While a good behind the scenes joke, I don’t think this means Gervais will join the cast as the new branch manager of Dunder Mifflin. It’s fun to speculate, but there’s no way it will happen.
