Get ready for Dallas on Wednesday with a refresher course

Want to watch the new series of Dallas on TNT on Wednesday in the US – it’ll be coming to Channel 5 in the UK later in the year – but never saw the original? Or perhaps you did see the original series, but given that was 20-odd years ago now, everything’s a little hazy now? Well, don’t worry. TNT has put together this behind-the-scenes trailer that interviews the cast while also giving you a brief run-down of what the show is all about and how it all started.
