Please help me find the brand of bike on the pictures
The frame looks very much like a generic Chinese singer speed frame. They are sold by countless brands.

I have a very similar bike which was sold as Leader, I think (I bought used). I replaced the rubbish brakes and finishing kit.



The sticker with the brand on the down tube is above the clear coat and peels off. It's quite flimsy. That indicates that the brands are an afterthought by the local distributors.

However, I suspect the bike in the original question was not made for the European market. There are no braze ons for the rear brake cable. It is attached with pipe- or p-clamps. Three finishing kit is probably custom added for the film.
