After being scouted in a London car park in 1995, Wek was one of the very first South Sudanese models to find global success . She has since appeared on numerous Vogue covers and modelled for the likes of Dior and Louis Vuitton.And the popularity of South Sudanese models shows no signs of waning - leading industry platform Models.com compiles an annual list of modelling's top 50 "future stars" and in its latest selection, one in five models have South Sudanese heritage.
in its article about the "11 young models set to storm the catwalks in 2025"."The expectation of what a model should be - most of the South Sudanese models have it," says Dawson Deng, who runs South Sudan Fashion Week in the country's capital, Juba, with fellow ex-model Trisha Nyachak."They have the perfect, dark skin. They have the melanin. They have the height."
Lucia Janosova, a casting agent at First Model Management, tells the BBC: "Of course they are beautiful... beautiful skin, the height."However, she says she is unsure exactly why fashion brands seek out South Sudanese models over other nationalities.
"I'm not able to tell you because there are lots of girls who are also beautiful and they are from Mozambique, or Nigeria, or different countries, right?" Ms Janosova adds.
Akur Goi, a South Sudanese model who has worked with designers like Givenchy and Armani, has a theory.Hugh-Odling Smee, Manager of Film Hub NI, said the idea to remaster 'Cal' originated when Queen's Film Theatre (QFT) was celebrating its 50th anniversary in 2018.
"Cal is a very important film to the QFT. It was really the first kind of Irish premiere that broke through, and it was very successful at the QFT when it came out."It's a very emotional film about a particular time in our history."
Mr Smee said he believes the re-release of Cal is important for young filmmakers in Northern Ireland, and described the film as an "important cultural touchstone"."People have seen it the odd time down the years, but the lion's share of people haven't seen it since it came out", he said.
