Continuity mistake: In the final scene at the party when the conga starts, Julie is at the front followed by Freddie, Jackie, Zammo, Mrs McClusky, Ronnie, Gonch, Louise, an extra, Calley, Robbie wearing an orange and green party hat and Trev. Then when the conga goes through the door and out into the playground the first 5 are the same, followed by Ronnie (who is now wearing a party hat), Gonch, Mrs Reagan, Jane, Hollo, Calley, Robbie (now wearing a yellow party hat), Cheryl and Trev (who is now wearing the hat Robbie was wearing). As the conga goes round the playground Hollo disappears from the line up and Louise moves further back.
Visible crew/equipment: At the presentation when Mrs. McClusky introduces Mr. Owen, you can see a boom mike shadow on his bald head.
Other mistake: Hollo goes into the hall where Perry is with Louise, Cheryl and Julie after Hollo has taken Perry's money for the bet he says "hope you win, Perry". Hollo couldn't know his name when he hadn't met Perry before or been introduced to him.
