The main cinema in Chatham is the Odeon which is very near to Chatham Dockside Outlet and the building is a part of the Dickens World complex. However, The Central Theatre, which is located on Chatham High Street, also sometimes shows films and details of these can often be found on the Medway Tickets Live website.
The Odeon cinema opened just over five years ago but before this the main cinema in Chatham was located near the High Street and went under a number of different of names before eventually closing down several years before the one in the Dockyard opened. Googling information on the history of this cinema brought me to this excellent guide on it’s history then I also found this one.
