The parent organization of the Maine International Film Festival plans to purchase the Railroad Square Cinema in Waterville. The Maine Film Center says the purchase advances its mission to enrich, educate and entertain the community through film and art. The film center has partnered with the cinema for 15 years to stage Maine’s premier film festival and other special programs. Film center Executive Director Shannon Haines says Waterville has a wealth of film resources, including one of the best-known art house cinemas in the country, an internationally known film festival and a new cinema studies program at Colby College. Haines says the Maine Film Center wants to bring those resources together to firmly establish Waterville as a vibrant center of film exhibition and education.
