Was not really a fan of the Andy Griffith Show but he really showed his acting chops in A Face in the Crowd.
Andy's best acting job by far, in 1974's "Pray for the Wildcats" he was pure evil. He missed his true calling as a heavy. [YT="A Hippie with money"]Lz6wYcvu0hc[/YT]
I believe aside from Ron Howard, there's a few of the kids that are still around. I know Jim Nabors (Gomer Pyle) is still around, Betty Lynn (Thelma Lou) is still around. Elinor Donahue (Ellie Walker) is still around. I'm not sure who else may still be around aside from them.
