The owners of Curzon cinema said its business was 'killed' by The Beacon's Cineworld.
The independent cinema in Langney Road closed in 2020 because it could no longer compete with larger cinemas nearby.
Commercial property sale site Realla listed the former cinema for a price of £1.4m. The website now says (as of August 1) the cinema is under offer and the full listing can no longer be viewed.
Realla says there is a 'potential development opportunity – subject to planning'.
The three-storey building, which was built in 1900, has a frontage to Langney Road and a yard at the rear.
The ground floor was used as a foyer and customer toilets, projection rooms and two screens with seating for 220 people each.
The mezzanine floor has more customer toilets and staff rooms.
The first floor has a foyer with customer toilets and projection room for a third screen for 520 people.
