Morgan Freeman's voice is arguably one of the most recognized voices out there. However, the rich and deep voice got a makeover with the help of a helium-filled balloon in the promotional clip of Science Channel's "Through the Wormhole".

The 76-year-old actor first hid under the shadows as he said, "In unusual situations," pausing a bit to suck on the balloon, "you don't always get what you expect." He stepped out into the light and continued in his normal voice, "But sometimes, unusual situations lead to new insight." He then took another shot at the helium.

Freeman is the narrator of the science series which returns with fifth season on June 4 at 10 P.M. In the promo ad, he was talking about gravity as the longest running unsolved mystery of the universe.
