Tomorrow Is Always Too Long, created by the artist Phil Collins, will feature people from across the city - from pensioners to animal rights activists, from poets to market sellers and inmates at Barlinnie prison .
The film project was commissioned by the city's Common Guild gallery and shot by cinematographer Michael McDonough, whose film credits include Winter's Bone and Starred Up.
It was made over a year by Collins, who met people in hospitals, schools, community groups and social clubs and asked them to sing, make predictions and dance, among other activities.
The results will be presented as if the footage is in an "imaginary public-access broadcast produced with a cast of Glaswegians from every walk of life to whom Collins opened the doors of a 1960s TV studio."
Collins, a Turner Prize-nominated artist whose father was from Glasgow, has also collected wedding photos from Glaswegians for the film.
The artist, who was born in 1970 and has twice been resident in Glasgow, has made a series of short programmes within the film, scripted by the writer Ewan Morrison.
Music for the film has been made by Cate Le Bon, Mogwai's Barry Burns, Golden Teacher and the Royal Scottish National Orchestra.
The film showing will take place on July 19 on LED screens set up in Queen's Park's Old Rose Garden.
The project is part of the Glasgow 2014 Cultural Programme.
Collins said: "Who would have thought that my love affair with Glasgow would result in a night out in the park?
"Each encounter and exchange along the way has been a riot to say the least, and if the work can communicate a fraction of the joy I've had making it, I'll die a happy man."
