 Pemberton and Shearsmith , in addition to writing and starring in " Nana 's Party " , directed the episode . This was the second episode they jointly directed in the second series after " Cold Comfort " , their directorial debut . The pair did not know , while writing for the series , which episodes they would be directing , meaning that their writing was unlikely to be influenced by the knowledge . Pemberton and Shearsmith had always intended to try directing , and the second series of Inside No. 9 offered them the opportunity . David Kerr , who had directed all of the episodes in the first series , was unable to return for the second . Guillem Morales and Dan Zeff each took on directorial duties for two episodes , while Pemberton and Shearsmith decided to direct the remaining two . Shearsmith said in an interview that the pair had considered directing episodes in which they did not appear much , but scheduling concerns left them with " Cold Comfort " and " Nana 's Party " ; both episodes feature the writers quite heavily .
