Watch full movie online. Mercy, the Mummy Mumbled pokes fun at both mad scientists and the Egyptian mummy craze that followed the discovery of King Tut's tomb early in the 20th century. A young man wooing the daughter of a scientist hatches a get rich quick scheme when he spots a classified ad searching for "a mummy for experimental purposes." While he wraps up a phony for the scientist, two Egyptian agents (outfitted in a crazy mix of ancient fashion and modern style) tracking stolen relics get tangled in the confusion.
