The web search results mention Cinema Day and HK$30 tickets for 2026 and May 10, confirming the concept of discounted tickets for Cinema Day. However, none of the provided evidence sources independently corroborate the specific claim that 'Hong Kong residents flock to theatres to buy advanced HK$30 Cinema Day tickets' as a current, single event, nor is there enough evidence to confirm the 'flocking' aspect across multiple independent sources. The evidence points to the *existence* of the promotion, but not the specific action described in the claim.

The evidence provides specific details about STAR CINEMA in Tseung Kwan O, including its address and general information. However, none of the provided sources confirm the specific event details: that customers queued 'from as early as 10:30am' or that this was for 'discounted tickets for films screening this Saturday'. The sources are general location/info pages.

This claim combines specific details (10:30 AM, Wednesday, Star Cinema, Tseung Kwan O, Saturday tickets) that are not independently corroborated across the multiple sources provided. While sources confirm the location (Star Cinema in Tseung Kwan O) and the general concept of ticket sales, the precise timing and sequence of events described in this claim are only suggested by the context of the search results, not confirmed by multiple independent reports.
