Tickets will be sold at a flat rate of HK$30, the same as in the past, at all 53 theatres.
More than 70 films are expected to be up for selection.
They include such films as The Last Dance and Twilight of the Warriors: Walled In, which have been nominated for the 43rd Hong Kong Film Awards.
Tickets will be up on sale three days ahead of the event at noon.
Timothy Yuen, executive committee chairman of the Hong Kong Theatres Association, believes the number of moviegoers will be similar to those in previous years.
“Given the success of the first and second Cinema Days, we are confident that this year we can achieve the same number, or even more than the last two years,” he said.
Yuen encouraged the public to enjoy the event with their families to celebrate Mother’s Day, that comes a day after Cinema Day.
At least two theatres have shut down this year, and Yuen emphasised that the content and quality of movies are crucial in luring moviegoers.
Each person can buy a maximum of four tickets in-person per time, while online purchases are subject to restrictions imposed by individual cinema chains.
The event attracted over 203,860 moviegoers last year, a slight drop of 8 percent compared to the inaugural Cinema Day.
