Hi! I think that this formal thing (I mean, the credit and uncredited directors) should be revised and corrected because it is unfair for the uncredited director not to appear, at least, in the data. For example Orson Welles. He directed some parts in "Black Magic", the opening in "The Southern Star" but as uncredited director. Or David Leitch in "John Wick", as many others. That is pure formality. It is important that have to appear in TMDB and Letterboxd as credit or uncredited director not only because he did direct but also because his authorism is present. I hope you change this (I mean that he could appear) and revised. Thanks!
