GREENOCK actor Martin Compston is on call to get the last series of Still Game under way - when he appears as a mobile phone salesman in the first episode.

Viewers will see Martin serving Jack and Victor in his shop when the final series starts on Sunday at 9pm on the new BBC Scotland channel.

The local lad says he has grown up watching the iconic show, making it a huge privilege to play a part in the final run.

Martin, now based in the United States, said: "It is an institution and one of the best Scottish TV shows of all time.

"I spend a lot of time on the road and I’m always sticking it on to watch as it reminds me of home.

"It’s a show you can watch with your mum and dad and whenever I was away on bus trips with the football teams, we’d put it on and watch for hours and everybody would be happy.

"Anytime I feel a wee bit homesick in Las Vegas I stick Still Game on."

Martin squeezed the scenes for Still Game in between his hectic Line of Duty filming schedule.

He said: "I come across Jack and Victor when they’re trying to buy themselves a couple of mobile phones and they come into my shop.

"It was surreal standing across from the two of them.

"Luckily I was filming Line of Duty at the same time so I was able to pop over from Belfast and shoot my scenes.

"It was an epic day.

"To see the boys do their thing was immense."

Show star Ford Kiernan says it was 'great' having Martin around on set.

He added: "He came to visit us on set a couple of years ago so it was wonderful to have him filming with us this time."

Sidekick Greg Hemphill added: "Martin had expressed a love of the show and is a big fan of Still Game and it’s always nice to have people like that around, people who have done so amazingly in their own line of work.

"He’s one of the biggest stars in the UK at the moment so for him to come in and spend a bit of time with us was fun."

Martin says he was 'gutted' when it was announced that Still Game is coming to an end - but he isn't giving up hope that it could make a dramatic comeback in the future.

He said: "I know the boys are saying it’s done but the fact that they’re playing old guys, 20, 30, 40 years older than them means that there’s so much scope for them in the future.

"They could literally bring this show back in 30 years time – just using less make-up!"
