Bookish-looking American actor King Donovan was first seen on Broadway in 1948's The Vigil and on screen in The Man From Texas (1950). Though he appeared in dozens of films, Donovan is best known for his participation in such sci-fi classics as Beast From 20,000 Fathoms (1953), Magnetic Monster (1953) and especially The Invasion of the Body Snatchers (1956). Musical comedy fans remember Donovan for his portrayal of the saturnine assistant director in Singin' in the Rain (1952). His many TV appearances include the recurring role of Harvey Helm on the Bob Cummings sitcom Love That Bob! and Herb Thornton on the 1965-66 family comedy Please Don't Eat the Daisies. Long married to comedienne Imogene Coca, King Donovan frequently co-starred with his wife in such stage productions as The Girls of 509 and his last theatrical effort, 1982's Nothing Lasts Forever. ~ Hal Erickson, All Movie Guide
