Some people have had the urge to "update" older films using modern technology. For example, there has been a great deal of "colorizing" older black and white films. Similarly, there has been a lot of remixing of the audio of older monaural films to surround sound. Was there ever a time when people "talky-ized" silent films? This could be accomplished by having actors speak out the actual or implied script, perhaps with music or foley effects. I don't remember ever seeing it but am curious if this was ever attempted. I do know that many classic silent films (e.g. Birth of a Nation) are generally presented on DVD with musical accompanyments.
