I just watched these two shorts on Youtube. The first was filmed downtown Korat in 2012; the second probably in the Saraburi/Nakhon Ratchasima border area in 2013. Both in a slowly spoken Thai, with English subtitles: good exercise for your language learning. Altogether, they last just about 25 min.
The first,
Scavenger, is a documentary about a poor man living with his family in a dump along the railway track downtown, without running water or electricity, but taking life very much philosophically ("If I was rich, I'd be just as happy as I am now"). Film is 5 years old but I think not much has changed over there in the meanwhile. We also see him riding his bike in downtown streets: maybe Trok Samorai at around 0:35; somewhere on Mitthapap at 0:47; accessing Jomsurangyard Rd, opposite
Wat Jaeng Nok, at 3:30.
The second,
Clouds of Memory, is about Alzheimer disease striking a once active and successful, now old and lonely businessman. He and his friend talk about how good or bad it is to recover old memories, and about what really counts in life.
PS: Final credits to
Scavenger mention about a so-called "Soi Bele", at 8:56:
And (featuring) the people of Soi Bele. That puzzled me because I never heard about it before, and it doesn't appear on any map I can lay my hands on. Then a Thai friend explained to me that it's probably a misunderstanding. At 6:04 the man describes settlements in that street as being totally unauthorized: "soi pen tuean pailoei"
ซอยเป็นเถื่อนไปเลย. However, he pronounces that "pailoei" in the local way, sounding like "bele". If editors of final captions were not from Korat, they may have misunderstood it for the soi's name.
