Watching holiday movies is as much a part of tradition this season as drinking eggnog, decorating a tree, or slogging it through a packed black Friday sale at the mall. We watch these beloved flicks over and over and their age and appearance become fixed in our minds. So might seem a bit disconcerting to see that, say, Ralphie from "A Christmas Story" is all grown up. We've put together this gallery of kid actors from holiday movie favorites then and now. Check it out.
