Lionpower from MGM: "Lionpower from MGM" (1967) is an exciting 60's promotional short subject, which showcases MGM's releases for the 1967-68 film season under a "five seasons" theme--fall, winter, spring, summer--plus a "fabulous fifth season". The main music is set to the rousing theme from "The Magnificent Yankee" composed by David Raksin in 1950. The promo is narrated by some of the best voice-over actors of the time, and is an excellent time capsule of a by-gone era.
