NWA The Movie 2015 - No MC Ren ?

I was hotter then a fire cracker this morning when I heard and seen the official photograph of Ice Cube, Gary Gray, Dr. Dre and 3 young men kneeled down in front of them who will be potraying ( acting) as Ice Cube, Eazy E, and Dr. Dre ! Were is 1/4 of NWA MC Ren ? He is known by far by everybody the best lyriclalist Mc out of all of them! How can you tell a true story if 1/4 of the group is not being potrayed ? I like some answers because at the age of 19, I first heard and bought NWA " 12" inch single " Dopeman " then " Boyz N the Hood " !  And from the years of 1986 untill through 1993 I bought all of Ruthless Records, Ice Cubes and Dr.Dre so like many people who helped them get rich, once again, How are you going to make a supposely true Movie with out MC rEN ?
