Next was '' Prae Dum '' ( '' Black Silk '' ) , which is regarded as Thailand ’s first film noir ( though '' Country Hotel '' had film noir elements as well ) . It is regarded as Rattana 's best work . He performed almost all the major tasks himself , acting as writer , producer , director , cinematographer and editor . For his efforts , '' Prae Dum '' was included in competition at the 11th Berlin International Film Festival in 1961
