Ben Stiller is a noted writer, director and performer of Hollywood comedies, who has headlined such blockbuster hits as There’s Something About Mary (1998), Zoolander (2001) and Tropic Thunder (2008). He is not necessarily the first name to spring to mind when thinking about horror movies, yet in 2008 he and his business partner Stuart Cornfeld produced The Ruins, a rarely seen yet stunningly effective horror film. It is a film as relentless as it is bleak, filled with dread and constantly rising tension. It is a film that gets under your skin – in the case of its protagonists, quite literally so.
