Director Benny Boom revealed the late rapper was to star in "All American" too.
Filmmaker Benny Boom said the rapper was supposed to star in the biopic about Tupac Shakur, who was also gunned down in his prime.
"Nipsey was supposed to play Snoop... we wanted him to play Snoop in 'All Eyez On Me'," Boom said. "We didn't have any other person that we wanted to play him."
Boom said because of Nipsey's busy music and touring schedule, as well as his dedication to community work, they couldn't get the timing to work.
"It's crazy because I didn't realize, as much as I knew Nipsey — I didn't realize how much he was driving things in his community," the filmmaker said. "And to take him out of LA for that amount of time that we needed to come to Atlanta where we shot, would've just threw him off his square a little bit. Just the timing didn't work out."
The role of Snoop was ultimately played in the 2017 film by newcomer Jarrett Ellis.
"I'm definitely upset, cause Nipsey was my guy," Boom added. "I am upset that we didn't get an opportunity to have him in the movie."
Nipsey was shot dead outside his clothing store in South LA on March 31.
According to Boom, before he died he was also lined up to play a key role in The CW show "All American".
In the series Demetrius Shipp Jr, who portrayed 2pac in "All Eyez On Me", plays a Crenshaw gang leader, having been introduced to the producers via Boom.
While Nipsey sadly never got to act on the show, his real life storyline will be introduced in the upcoming second season.
"From what I'm hearing from the writers, this season, there's going to be a lot of Nipsey stuff in there," Boom added.
