African-American actor Bill Henderson may not be the same Bill Henderson listed in the British Attack on the Iron Coast (1968), but he definitely did appear in Mother, Jugs and Speed (1976), Inside Moves (1980) and Smart Alec (1986). Those who have catalogued the many failed TV series of Tim Conway will recall Henderson as Mello, blind nightclub pianist in 1983's Ace Crawford Private Eye.
At least Ace Crawford made it to the airwaves; 1987's Kingpins, a comedy set in a bowling alley which featured Henderson in a supporting role, never got past the pilot stage. Bill Henderson's most prominent recent screen performance was as one of several dude participants of a cattle drive (he's the father in the father-son team) in the 1991 Billy Crystal comedy City Slickers. ~ Hal Erickson, All Movie Guide.
