The movie was called "Power of Love." It came out in 1922 and soon disappeared.

But Arts and Entertainment Editor Bob Sokolsky says it left an intriguing trail because it is believed to be the first to employ the 3-D process.

Sokolsky cites several examples of what they have led to -- not all of them successful -- as well as what they might lead to.

Possibilities, he says, range from production techniques to new forms of distribution.
