One cute thing I've seen before is in place of the traditional 'tink tink tink' on your wineglass to get the bride and groom to kiss, the guests are encouraged to think up classic movie kiss scenes for the bride and groom to re-enact. Think the upside-down spiderman kiss or that pottery wheel scene from ghost... it could be really interesting!
Also, not sure if this will help or not... but here's a fantastic wedding planning site I know of with loads of vintage and glamour inspired details. There's a few things I could see lending themselves well to your theme.
