The 31-year-old writer-director also attended a press conference and dished about the record-breaking success of his hit film Black Panther and the possibility of making a spinoff with the female leads.
During a almost two-hour-long masterclass at the Cannes Film Festival, Coogler was asked if he would ever make such a film.
Martin - who has also starred in the "Hobbit" movies - said it's important to keep the potential influence of films in perspective. "They did it in the comic-book version".
"That part of the movie you feel like you're watching something fresh and new".
The year's most lovable film Black Panther has nearly too many timely messages to count, which is one of the reasons it became the highest-grossing superhero movie, ever, a month after its release. "That part of it was exciting", Coogler shared.
Letitia Wright, who plays Shuri, is ready for the call. "These actresses could easily carry their own movie", he said.
Reflecting on the response to "Black Panther", Martin said: "People have felt a need for it, and people don't always feel a social need to go and see a film. I would watch a movie with them!"
Now you just need the rest of Wakanda to get on board. Thats one of my favourite parts of the movie when I watched it, and I didnt expect that.
