I need some help for a TL I'm thinking of writing

[ColeMercury]

It's a pop-culture-centric TL, with a POD in 1974 of George Lucas deciding to take a break from writing Star Wars so he can take up Francis Ford Coppola's offer of directing Apocalypse Now.

What I need is a black American actor who would have been about 17 years old in the year 1975 (or could pass for that age), to play the role of "Mr Clean". In OTL the role was played by none other than Laurence Fishburne, who lied about his age and was actually 14 years old when filming began in 1976 -- but in TTL filming would begin about a year earlier. They should be somebody who actually was an actor at the time.

I could cheat and say "Mr Clean was played by an unknown actor who sank back into obscurity immediately after and never acted again" but I want to see if I can do better than that. So, does anyone have any ideas?
