Based on True Events

I took the ghost of Nelson Mandela to see the movie, Nelson Mandela: The Long Walk to Freedom. 

But we accidentally went to the wrong theater and unbeknownst to us saw A Madea Christmas.

Halfway through the movie I asked the ghost of Mandela how true to life it was. He said it was pretty accurate because it reminded him of what it felt like to be imprisoned for twenty-seven years.
