The second monthly Week of Siam series of classic Thai films starts on Thursday, April 23, at House cinema on Royal City Avenue in Bangkok. This month's theme is "Serious Week", devoted to social realism.
Among them will be three films by Permpol Choei-arun: Muang Nai Mok (A Town in Fog, เมือง ใน หมอก, 1978, on 16mm), Cheewit Budsop (ชีวิต บัด ซบ, 1976) and Muang Khorthan (Beggar’s Town, เมือง ขอทาน, 1978).
There's also Khon Klang Dad (คน กลางแดด 1987), Laa (ล่า, 1977) and Theppajao Baan Bangpoon (เทพ เจ้าบ้าน บาง ปูน, 1980) by Pakorn Prompitak.
None of the films will have subtitles, as far as I can tell.
And another thing, House cinema's website might be having difficulties, and in case you encounter trouble, try their backup, the House cinema blog at Exteen.
The Week of Siam film series continues on the last week of each month until August.
