Genevieve nnajis directorial debut to premiere at 2018 tiff

I think there may be some misinformation here!

Genevieve Nnaji is a Nigerian actress, producer, and director, but I couldn't find any information that suggests her directorial debut premiered at the 2018 Toronto International Film Festival (TIFF).

However, Genevieve Nnaji did make her directorial debut with the film "Lionheart" in 2018, which premiered at the 2018 Toronto International Film Festival. "Lionheart" is a Nigerian comedy-drama film that tells the story of a woman who tries to save her family's business from being taken over by her uncle. The film was well-received at TIFF and went on to become the first Nigerian film to be submitted to the Oscars for Best International Feature Film.

So, to correct your statement, Genevieve Nnaji's directorial debut "Lionheart" premiered at the 2018 Toronto International Film Festival, not her first film as a director.
