Time-travel can be a very risky and finicky concept to add to any work of fiction. It could lead to viewer confusion, or a decretion of tension and stakes as, you'd imagine, if a character were to make a mistake or die, you could simply rewind the events and prevent such a devestating occurence from ever happening.
So when Star Wars Rebels seemingly introduced the prospect of travelling through time during its final season, many fans of 'the galaxy far, far away' were quite wary - to say the least. In a featurette, which features on the fourth season's upcoming Blu-ray release, series producer Dave Filoni explains the mysterious timey-wimey realm in more detail - clarifying that sequence doesn't necessarily confirm time-travel.
Here's what Filoni had to say to CinemaBlend on the topic:
I don't really think of it as time travel. It's not really a thing where you go through one door and out another in a different time. The world between worlds is really about knowledge and gaining knowledge. As the Dume wolf says, what's in there is knowledge and destruction. You can gain knowledge of the future or futures that may happen, and you can see things that happened in the past. You can at times choose to alter them, but it's perilous to do so and when you alter something you don't know if that's not the way it always happened. So destruction is the other half of what's in there.
Filoni went onto explain that this realm was merely a manifestation of what Luke was told during The Empire Strikes Back all the way back in 1980.
When you go through these doorways, you're in peril of destruction because you're missing all sorts of things that would have happened or things would've happened otherwise, you know, so it's a dangerous game but it's not something we're here going in and out of different doors. It's an extension of the Jedi's ability to perceive the future and the past, as described in Empire Strikes Back.
What do you think about Filoni's comments? Would you like to see time-travel introduced to the Star Wars universe?
