For the first three series of Still Game the creators used Scottish words and spellings (for example: 'Faimly'). As Series 4 was shown in England and Wales too, from that point on standard English was used to title episodes. This was done to help national audiences better understand the titles. Additionally, the later series, characters use notably less Scottish slang and terminology. Presumably again, this was done to make the show more accessible to national audiences.
Just before the fifth series started filming, a pest control team had to be called in to the studios as rats had infested Navid's shop set. The alarm was raised after Jane McCarry (who plays Isa) found a dead rat on the set.
At one stage Still Game was attracting over half of the available TV audience in Scotland.
Still Game began as a skit on Ford Kiernan and Greg Hemphill's comedy skit show Chewin' the Fat. The skit comprised of Jack, Victor, Winston and Tam sitting in their favorite pub singing inappropriate songs.
Before the series was produced, Kiernan, Hemphill and Riley produced a live stage show written by Hemphill, with a cast total of three, including themselves and Paul Riley (Winston), the show was a great success and became the catalyst for Chewin' the Fat and Still Game.
Throughout the series, a brand of lager called "Fusilier" pops up in various places including The Clansman and Navid's convenience store. This is a reference to Chewin' the Fat which ran a series of 'fake' commercials for the fictional beer under the tagline 'It's never too early for a Fusilier'.
Whenever any of the main characters are listening to radio or television, Ford Kiernan's voice can usually be heard as the voice over.
Greg Hemphill had to wear brown contact lenses for the character of Victor McDade to make his eyes look darker as his own eye color - a rather vibrant pale blue - stood out far too much against the aging makeup.
The aging makeup and wigs the lead cast members sported were so convincing that whenever they filmed on location amongst the general public, no one could tell their real ages. On more than one occasion, Greg Hemphill and Ford Kiernan were approached by women in their sixties and asked out while costumed as Jack and Victor, while Paul Riley was offered help crossing a road while feigning Winston's limp.
All of the cigarette packets behind Navid's counter in the convenience store were empty, and most of the liquor bottles were filled with colored fruit juices. The foodstuffs in the set however were real although some of it was past the expiration date.
The items in most of the sets (other than the Clansman and Harrid's store) comprised of vintage items bought from second-hand stores, auction houses and charity shops as it was impossible to get vintage style furniture other than having it recreated.
The director and producers had to fight with Health and Safety inspectors to keep the couch in the set of Victor's flat as it wasn't flame retardant and the character of Jack would often smoke a pipe while sitting upon it. Eventually, a compromise had to be made in which the fabric was treated to be flame-proof in order for the couch to remain on set for the rest of the series.
Jack is referred to as being two years younger than Victor in the series while in actuality, Ford Keirnan (Jack) is eight years older than Greg Hemphill (Victor).
