Many will recognise him as the troubled teen from Grange Hill back in the eighties.
Now, Lee MacDonald will be returning to our screens to take part in another hit series — Eastenders.
The 50-year-old played the beloved character of Sammy “Zammo” McGuire.
He was remembered by most as the cheeky lad who unfortunately turned to heroin later on in the series.
Starring on the gritty drama from 1982 till 1987, Lee was one of the most recognisable faces on the show.
His role as an addict eventually led to the cast releasing a chart-topping hit titled Just Say No, as part of a nationwide anti-drugs campaign.
After leaving Grange Hill he became a boxer while juggling some small acting roles in shows like The Bill.
After a while, he left acting altogether and opened up his own locksmith business.
The producers of Eastenders have somehow convinced Lee to get back in front of the camera, as he will join the cast for two episodes this summer.
Playing a bus driver, his character will compete against landlord Mick Carter, played by Danny Dyer.
The two will go head to head in a bid to win gig tickets in a local radio competition.
Lee isn’t the first Grange Hill star to appear in Albert Square — his former costars Todd Carty and Susan Tully have also starred in the soap opera.
Chatting with The Sun, he said: “I am absolutely chuffed to bits and so excited to be briefly joining the cast of EastEnders.
He continued: “I can’t say too much yet but watch this space. Top banana!”
According to the newspaper, a source added: “Nobody saw this coming but it’s a great nostalgia trip for viewers.”
