Dean Smith and Tom Gibbons who play best friends, are real life best buddies and have been since their early teens.
The script was originally written in 1999, and was the winner of the first ever Oscar Moore Screenwriting Award in the UK - and was optioned to be made in 2001. The deal collapsed before the film was produced, and the script was shelved for 20 years before being completely rewritten in 2022/23 with the actors Dean Smith and Tom Gibbons for the leads.
The writer had previously worked Smith and Gibbons on an internet show called 'Dylan Ogden' in 2007 when both actors were in their teens and starting out.
The updated script bares little resemblance to the original 2001 draft, other than both stories centre on best friends on an all day drinking session.
