Production
Like Leigh's previous film "The Permissive Society", "Knock for Knock" was produced by BBC Birmingham as part of their Second City Firsts strand. In an online Q&A for The Guardian in 2000, Leigh said it was 'experimental for the time' as it was recorded in one take with multiple cameras. The tape was wiped by the BBC after broadcast and no copies are believed to exist. According to Leigh, it was 'wiped by a crackpot committee because of a "shortage of space".' He went on to say he would pay 'good money' if anyone could find a copy.

Critical reception
The film received a very positive review by Time Out who said it was 'the funniest thing on the box for months' and that Kelly gave the performance of the decade. Leigh himself described Kelly's performance as 'incredible and hilarious'.
