Pen-Ek Ratanaruang (RATANARUANG Pen-Ek / เป็นเอก รัตนเรือง) is a Thai writer, director, born on Thursday, March 8, 1962, in Bangkok, Thailand.
All Thai names have meanings. 'Pen-ek' literally means 'is the best'. 'Pen' is the verb 'to be' but since Thai has no conjugations, it can mean anything from the present singular 'is' to 'are' to 'being'. 'Ek' is 'first' or 'the best'.
In each of the first five films he directed, he included a character named Noi. The word "noi" in Thai means "few" or "less.".
