Book excerpt: In Silent Topics, film historian Anthony Slide looks at various under-discussed and generally undocumented areas of silent film. The two lengthiest essays discuss the release of British silent films in the United States and the contribution of gays and lesbians to American silent film. Other essays examine the cost of silent film production, the "Great Events" series produced by Technicolor in the 1920s, and the manner in which early sheet music exploited silent film personalities. There are career essays on the screen's first special effects specialist, Roy Pomeroy, actor/minister Neal Dodd, and Margerie Bonner, the wife of novelist Malcolm Lowry. Silent Topics also includes the only known interview with the most prominent of silent film composers, David Mendoza, as well as a personal discussion on the lack of talent among a number of silent screen actors and actresses.
