The sixth series of BBC Two's Inside No.9 airs its penultimate outing tonight (7th June), but that doesn't mean the dark comedy anthology - which won Best Scripted Comedy at the 2021 BAFTA TV Awards - has run out of memorable guest stars.
Reece Shearsmith and Steve Pemberton's latest offering will see an actor make a second appearance in the series for the first time ever, with none other than Sir Derek Jacobi returning after lending his voice to series three episode The Devil of Christmas.
However, Jacobi will actually be appearing on screen in the fifth episode titled How Do You Plead?, playing a famous but sickly barrister who has a rather memorable night that will test his resolve to the very end.
The acting legend will be joining an already terrific line-up of guest stars from this latest series, including Fleabag's Sian Clifford, Sherlock's Lindsay Duncan and Line of Duty‘s Adrian Dunbar who played himself in a memorable episode.
