The Palace of Youth and Children where Nur, 55, works is one of just three functioning cinemas left in a city of 4.6 million people.
Today few visit the squat, concrete hall, its outside plastered with sun-faded posters for the years-old Indian action films it screens.
Although Khartoum's upmarket Afra mall has a screen, the Palace is a rare survivor of the heyday of the capital's cinemas.
Nur started working in the cinemas as a teenager in his hometown of El Obeid, before studying film engineering in Cairo and arriving in Khartoum in 1983, where he worked in three other cinemas. At the time Khartoum had some 15 cinemas, all packed on weekends.
"In the past, people used to call to reserve tickets and in the week there was a programme with English-language films on Sunday, Arabic on Tuesday," Nur says amid the whirr of his projection room.
"Cinema's in a bad state now. There's no cinema really," Nur sighs.
The Sudanese economy suffered badly after 1989, particularly when the United States imposed a trade embargo in 1997 over allegations that included rights abuses, and cinemas struggled to afford foreign releases, prompting many to buy cheaper Indian films.
The capital's open-air movie theatres -- auditoriums with hundreds of seats laid out in front of huge screens -- were worst hit. Fearful of demonstrations, Bashir's regime imposed a curfew around the capital for several months.
He helped set up the association to promote cinema in Sudan in April 1989, but the hardline Islamists who came to power with Bashir took a dim view of cinema.
"They did not outright say cinema was haram (religiously forbidden) or banned, but they took steps to decrease screenings," Ibrahim said, including closing the state cinema institution, a final blow for many cinemas.
One of the open-air cinemas, the Halfaya, limped on until 2005. Built in 1955, its peeling green facade looms over a quiet street. The only people using its 15-foot screen are the children of its caretaker, who use it as a goal as they play football.
