Film Colorization

I've always thought of film colorization as a visual effect that would be too costly to do on movies besides proving the point it is possible. I changed my mind recently when I saw the two probably most famous soviet black-and-white movies colorized.

The first one is "Seventeen Moments of Spring" (by Tatyana Lioznova, 1973)



and the second one is "Only Old Men Are Going to Battle" (by Leonid Bykov, 1973)



This last one shows a bit of the original movie at the beginning to give you a feel of the effect.
