Prince and Bigi Jackson joined their uncles Jackie, Jermaine, and Marlon at the Berlin premiere of the biographical film Michael as family tensions over the production became evident.The Antoine Fuqua directed movie features Jaafar Jackson as the legendary pop star but was snubbed by Janet, LaToya, and Paris Jackson who previously voiced disapproval of the project.While the film depicts the global icon from childhood fame to his legal acquittal in 2005, it is scheduled to reach German cinema screens on April 22 after this high profile debut.
