Are we watching the same films and TV shows anymore?

What happens when the films and TV programmes we grew up with aren't quite the same things we remember?This week, a mix of Doctor Who and Star Wars, with Christian Cawley, James McLean and Brian Terranova beginning with some surprising discoveries about Luke Skywalker's decidedly ordinary trousers and Han Solo's blaster, changing lightsaber props, and the surprisingly problematic dimensions of the Millennium Falcon.That leads us into the world of film and television restoration. What can modern transfers reveal that VHS and old television broadcasts concealed? And why might the Peter Cushing Doctor Who movies never make the jump to true 4K?Doctor Who presents another puzzle. The series has always contained changing props, models, sets, and continuity, yet fans seem remarkably willing to accept them. More recent projects such as The War Games in Colour take things further, effectively creating alternative versions of familiar stories.Then things get personal. James reveals that he edits songs he likes into what he considers their "correct" versions, leading to a discussion about fan edits, remixing, copyright and whether audiences have always customised the media they consume.As CGI, AI and increasingly powerful editing tools become available to everyone, could personalised versions of films and television become commonplace? And if we can all "fix" the things we don't like, are we still watching the same thing?
