• Although incorrectly described in the British Films Catalogue as having been shot on 35mm film,^[1] Bad Day was in fact one of the first independent feature films shot entirely in the UK using the Panasonic AG-HVX200 P2 camera.
• Notably this was the first acting performance in a feature film from Sarah Harding of the popular UK girl band Girls Aloud.^[2] Owing to release schedules her subsequent appearance in St Trinian's 2: The Legend of Fritton's Gold was released to the public before Bad Day.
• When it was decided that Sarah Harding's character in the film should have long, dark hair a wig was used to cover her distinctive short blonde crop.^[3]
• The visual FX supervisor for Bad Day had previously worked on The Da Vinci Code, commenting that the number of individual FX shots he completed on Bad Day exceeded those on this previous film. SVFX included greenscreen driving scenes, muzzle flash and squib/wound/blood enhancements, mic/wire removal, digital scene enhancements and day-for-night image manipulation.
• The original score was composed by Dominic Glynn who is best known for his work on the TV series Doctor Who.

Bad Day was released as a direct-to-video release on DVD and Blu-ray in the UK.
