Well that should settle the casting rumors!
Earlier reports claimed that Oprah was in talks to star as Pryor's grandmother Marie Carter, who raised him in her brothel.
The TV mogul tagged both Epps and Daniels in the caption of the cute pic and said, "Just finished a great 1st read session #RichardPryorMovie."
Meanwhile, Daniels wrote, "And we're off…Get ready y'all" next to the same image on his own Instagram page.
Epps, who beat out the likes of Eddie Murphy and Marlon Wayans (to name a few) for the role, also joined in on the Instagram bandwagon and posted, "making magic for Hollywood."
Over the weekend, he tweeted a pic of himself with the comedian's widow, Jennifer Lee Pryor.
"Had to kiss the ring of @jennferLpryor for the blessing ! you got to be strong to have been with the king," he wrote, showing that the casting has clearly gotten the stamp of approval from her.
But while Jennifer may be on board with the upcoming flick, it seems as though the comedy legend's children are not as enthused.
Jennifer tweeted a few weeks ago, "Every time I do a Richard Pryor project, the kids attack' 6 kids, 5 different baby mama's—nothing to do but feel sorry for them."
