TMZ reports that Bain passed away on Monday night in Livermore, Calif., of causes yet unknown. With the exception of a one-off appearance on the TV series Unforgettable in 2011, Bain has not acted since 1996, when he parodied his Diff'rent Strokes character on an episode of The Fresh Prince of Bel Air. Bain was also a starring player on Norman Lear's 1970s sitcom Maude, playing the uptight Dr. Harmon, a foil to Bea Arthur's title character.
His cause of death was unclear, but his daughter Jennifer told TMZ: "He was an amazing person. He was a lot like Mr. Drummond, but much more interesting in real life. He was an amazing father."
Bain's death leaves only one surviving member from his "Diff'rent Strokes" TV family. Dana Plato, who played his daughter Kimberly, died in 1999 of a drug overdose. Gary Coleman, who played adopted son Arnold Jackson, died in 2010 after a fall down a flight of stairs in his home. Only Todd Bridges, who played his adopted son Willis Jackson, remains.
When reached for comment, Bridges' manager had not yet heard of Bain's reported passing.
Bain is survived by his twin brother Bonar, and his three sons and one daughter...
