Larry Hagman aka the Mad Monk of Malibu

Actor -- via the Hollywood Reporter. Remembered either as a gleeful villain (J.R. in the TV drama "Dallas") or as a hapless, affable comic lead (Major Anthony Nelson in "I Dream of Jeannie"), Hagman
could actually act, as shown through his brilliant supporting performance as the translator for the U.S. President played by Henry Fonda in "Fail-Safe."

His mother was Broadway superstar Mary Martin. An epic partier, he later quit drinking alcohol and smoking (tobacco at least) and became a vegetarian.
