Re: NBA Players that ACT? Produce?
Not really clear what you're looking for here, but if you're looking someone more likely to be accessible than the above-mentioned superstars, I'd add the name Marques Johnson. An All-Star caliber player in the '80s, turned to acting after his career was cut short by injury - probably best remembered for pulling a gun on Wesley Snipes and Woody Harrelson in 'White Men Can't Jump' - seems to have worked steadily. Most recent credit - 'The Gambler'.
Rick Fox looks like a movie star and is very personable (and he could shoot the three) but I wouldn't call what he does acting.
Best of luck.
