Live Entertainment’s disc “Chaplin” is filled with plenty of small hidden features.Select “Cast&Crew” from the disc’s main menu. If you select “Robert Downey Jr.”, each one of the screens describing his career contains a hidden feature – mostly snippets from a video interview. Use your arrow up key to highlight the Charlie Chaplin symbol on each of those screens and then press “Enter” to start the extra. The same procedure works in some of the biography screens for Kevin Kline and Anthony Hopkins.
