skin-and-bones world of high fashion by launching her own line
of clothes for large ladies. While on vacation, she meets Tunde

Nigeria, and she discovers to her surprise that Tunde is strongly
attracted to her

Lost nko?
Can't really remember what happened but some man named Eko had some Nairas he brought to the forest...
How he got the Naira was traced to some town in Nigeria where he forced his brother(think he got Nigerian name). He persuaded the brother into giving him his Church Plane, he needed to transport drugs across the atlantic. That was why he needed the plane.
So, I have the opinion that Lost is there!

OP - The title of your thread is so wrong. What you mean is movies/TV shows that have portrayed Nigeria/Nigerians and not 'portrayed IN Nigeria' - none of those were shot IN Nigeria.

OP: The Title of ur thread is wrong just like villageboi noted.
Which brings me to the question- "do you even know what it is you are saying?"

Nigeria was mentioned in the movie Avatar.
