(written from a Production point of view)
Vincenzo Natali is a film and television writer and director who Bryan Fuller confirmed was a "producing director" of Star Trek: Discovery,  but left after what he described his "short voyage" with the show.  He never received any on-screen credit for his work on the series.
He is perhaps best known for his feature films Cube (starring Nicole de Boer), Cypher, Nothing, and Splice. He has also directed episodes of TV series such as Orphan Black (starring James Frain) and Hannibal.
In addition to this, he began his career as storyboard artist working on cartoon series including Beetlejuice, Fievel's American Tales, and also the feature film Ginger Snaps.
