Although the boys' holiday is set in Malia, Crete (Greece), the majority of external filming took place in Magaluf, Majorca (Spain)- with any signs mentioning the true location covered up, removed or replaced.
James Buckley, who played Jay; was 23 years old when the film was made. He was the youngest of the quartet who played 18-year-old school leavers. He was also the first to marry and have children.
Originally, Mark Donovan; who bullied the Inbetweeners in the TV series, was to have a larger role in the film where he would follow the lads to Malia, but the writers couldn't fit it into the script so the idea was scrapped.
In a deleted scene, Jay and Neil were seen in a tattoo parlour and decided to get their names tattooed on each other as a reminder of their holiday. When Neil looked at his on a mirror it says: "Jay and Neil Malia" but it actually says "Gay Neil" and Jay refuses to get his arm done. The tattoo artist assures him it is what he asked for, even though it wasn't. Jay assures Neil he knows a guy back home in England who would be able to remove it.
