'Straight Outta Compton' Director F. Gary Gray -- Marvin Gaye Is Straight Shakespeare!! I'd Do That Movie NOW, But ... (VIDEO)

We can hear the trailer now -- "From the man who brought you NWA's epic story, comes ... the Marvin Gaye you never knew."

"Straight Outta Compton" director F. Gary Gray broke the news to us -- no, he's not rushing to do another biopic, but confessed the one person that could change his mind is Marvin Gaye.

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.
