In this 90-minute special, Channel 5 celebrates one of Britain's most loved comedies of all time - Porridge. Packed with the funniest clips, along with insight and analysis from its writers, cast, crew and celebrity fans, this programme looks back at Dick Clement and Ian La Frenais's unique comedy classic.

Made five decades ago, Porridge is as popular today as it was when it was first made, and this exclusive documentary examines how the wonderful characters in Slade Prison revolved around Fletch, the late Ronnie Barker's inimitable comedy creation.

As well as those laugh-out-loud moments from the three series of Porridge, we look at the follow-up show Going Straight, Porridge: The Movie, the US remake On The Rocks, and the 2017 reboot starring Kevin Bishop and Ricky Grover.
