According to Deadline Hollywood, Marlon Wayans and Essence Atkins will star in an NBC pilot based on the veteran comic's life. Atkins will play the usual type A/alpha female she plays often (see: Half and Half from the early 2000s)and Wayans will be a goofy but lovable character (see: old episodes of Wayans Brothers, In Living Color in the later years and 90% of his film work.
On a related note, he's done with parodies and I'd say the timing is just right (Rhymes with Snitch). I saw Shades of Black a few weeks ago and maybe it's may age showing but there's nothing funny about prosthetic phalluses but here's the spoiler...Carol Brady is funny.
Finally, I hope he's reconsidered for the Richard Pryor biopic (see audition tape above).
