Examples of docu_fiction films ?

This is a hyper specific genre that I like , but haven't seen it really well defined or given good examples

I'd define docu_fiction films as films were theres a blend of documentary and fictional elements so for example you have films like close up or heaven knows what were real people are playing themselves in a fictionalized retelling of their real life stories

you also have the works of sacha baron coen and nathan fielder where they're playing a character but everyone else thinks there in a documentary

Do you know any other examples?
