There are a few possibilities:
* The title is slightly wrong. Perhaps it's a different spelling, like "Bye Mzungu!" or a variation on the title.
* It's a lesser-known film. This might be a film that was released independently or had a limited release.
* It's a TV series or documentary. It could be a television show or documentary that you're thinking of.
To help me find the correct film, could you provide more details, such as:
* The exact title as you remember it.
* Any other information you know about the film, such as the genre, plot, or director.
With more details, I can help you find the correct film and its cast.
