We can hear the trailer now -- "From the man who brought you NWA's epic story, comes ... the Marvin Gaye you never knew."
Gray started riffing about the ex-Motown superstar the second our photog asked what he'd like to do to follow up his huge 'Compton' success.
Of course, there have been a couple of failed attempts to bring Gaye's life story to the big screen -- one was even supposed to star Lenny Kravitz.
So, will Gray use his 'Compton' clout to finally make a Marvin movie happen? Check out the clip.
All we can say is ... Let's get it on!
