SAR tourism officials and film veterans on Friday hailed the launch of a new exhibition that allows people to take a deep dive into iconic 1980s life at Kowloon Walled City using replica movie sets, saying the attraction will create new economic benefits.

The launch of the three-year show – "Kowloon Walled City: A Cinematic Journey" – came after the government on Tuesday unveiled a total of nine tourism hotspots, including Kowloon City, to woo tourists for in-depth tours.

In an opening ceremony for the exhibition, Deputy Chief Secretary Warner Cheuk said the show – which is located at Kowloon Walled City Park, the site of the original slum city – is much bigger than two earlier versions of the exhibition that were held at the airport and Kai Tak.

The exhibition features replica movie sets from last year's "Twilight of the Warriors: Walled In" hit film.

"The film scene exhibition not only attracts more visitors to the park but also connects to scenic spots in Kowloon City, such as the Kai Tak Sports Park, urban views and Thai-style cuisine in the district," Cheuk said.

"Through various tourist routes within the area, tourists can experience the authentic culture of Hong Kong and taste different delicacies.

"At the same time, this can boost consumption in the area and create economic benefits."

The exhibition is the third to feature the hit movie and will present more iconic sets from the film, including a barber, tailor and fish-ball shops as well as a precursor to today's cha chan teng.

Visitors will be able to explore the exhibition using interactive technology to experience the lives of residents living in the walled city back in the 1980s.

Augmented technology devices will be rolled out from the third quarter of this year to give visitors a better experience.

Hong Kong Film Development Council chairman Wilfred Wong said the show will allow visitors to learn more about Hong Kong's history.

He added that large projection screens installed on rooftops will give people a sense of what days and nights are like living in Kowloon Walled City, with special sound effects, such as of planes reverberating over the district.
