The two silents are being restored as we speak. Ron Hutchinson of the Vitaphone Project:
Colleen Moore's final silent, WHY BE GOOD? (FN/'29) was long believed to be lost. About 10 years ago while introducing one of my Vitaphone shows at NYC's Film Forum, I mentioned I had just acquired the Vitaphone disks (music and effects) for this feature but, sadly, the film was lost. Film historian Joe Yranski was sitting in the front row and yelled out "No it's not! I know where it is!". The crowd cheered, and so began a decades-long effort to get the film back to American and restored...[t]he print of Moore's next to last silent with Vitaphone track, SYNTHETIC SIN (also thought lost) is also being repatriated now and restored.
