Who advice Jennifer Hudson in not consulting Winnie Mandela in acting her???

"I have absolutely nothing against Jennifer, but I have everything against the movie itself," she told CNN.  "I am still alive and I think it is total disrespect to come to South Africa, make a movie about my struggle and call that movie some translation of a romantic life of Winnie Mandela. I think it is an insult." 
 this is Winnie mandela's words during her interview with CNN about the new movie based on her life which jennifer Hodson is a starring.
when Jennifer asked she said that she wanted to speak to Winnie , but she was advised it would be a bad idea!!!!!!!
What were you thinking Jennifer, acting someones life who is still alive without even spoken to her?
