Morgan Freeman is an actor as infamous for his distinctive voice as he is for his movies roles.

His low, baritone, deep voice has narrated many a film and voiced many a character in his time.

To publicise its docu-series "Through the Wormhole," the Science Channel created an ad with Morgan Freeman and a helium filled balloon.

Freeman doesn't actually give us any amazing insights in the ad, but hearing his inner-child's voice is reward enough.
