River City actor Johnny Beattie has added his name to a parent-led campaign to prevent Glasgow City Council shutting St Oswald's Secondary, an Additional Support for Learning (ASL) school in Cathcart, and move the pupils into classrooms at St Margaret Mary's Secondary in Castlemilk.
A group of concerned parents have opposed the move and are campaigning to retain the current school.
They are concerned the children will not cope with a mainstream environment.
The comedian and actor, who has more than 50 years show business experience behind him, has a family member at the school.
He has submitted a letter to James Dornan SNP Cathcart MSP, who is backing the campaign to retain the school at the current site.
Mr Dornan said he has no concerns over shared campuses, but is worried about forcing an ASL school into a mainstream school and the upheaval it could cause for children.
Mr Beattie's great niece is a pupil at the school and he said she has been very happy there.
Mr Beattie said: "The idea of a move is very upsetting for the children and their parents.
"It's important that the interests of the children are considered."
The actor, currently starring in Scottish soap River City as Malcolm Hamilton, lives in Glasgow and said he sees his nephew and great- niece regularly and is aware of the situation at the school.
Mr Beattie's letter states: "I would like to lend my support to the concerned parents of the pupils at St Oswald's Secondary School.
"The special needs of these young people should be the top priority in any future negotiations, for their sake. We trust Glasgow City Council will listen to their concerns and save St Oswald's School."
The consultation on the proposed move closes next week, when a decision will then be taken after all the submissions have been considered.
The council said any move, if approved will not take place until August 2014 and has said in the meantime officials would be seeking to be working with parents to discuss concerns about the new environment they have.
Parents and the children expressed fears over the potential for bullying at a mainstream school and there were worries over children being in a bigger and noisier environment, considerable different from their current circumstances.
Mothers spoke of the anxiety the uncertainty has caused among their children, many of who don't react well to change.
Some parents said they understood there were problems with the physical condition of the building, but pointed to Labour's commitment before the last council election in 2012 to rebuild or refurbish every primary school in the city, asking why it doesn't apply to St Oswald's.
The council has said there is no suggestion of any children who do not have the capacity to cope with the new environment being forced to move to St Margaret Mary's.
Parents from the school are expected to hand in their submissions to the consultation to council chiefs at the City Chambers today.
St Oswald's is a Catholic secondary school for pupils with additional support needs including autism.
The school has 18 pupils from S1 to S6 offering classes across a range of subjects including English, maths, science, social subjects and as well as enterprise and employability.
The school aim, according to its handbook is to ensure that every pupil is actively engaged in their learning and feels safe, happy and valued.
