By wrenching this increasingly outdated revenge play into the present, Shakespeare forced his contemporaries to experience what he felt and what his play registers so profoundly: the world had changed. Old certainties were gone, even if new ones had not yet taken hold. The most convincing way of showing this was to ask playgoers to keep both plays in mind at once, to experience a new Hamlet while memories of the old one, ghostlike, still lingered. Audiences at the Globe soon found themselves, like Hamlet, straddling worlds and struggling to reconcile past and present.
