In The Worst Thing Ever?, Darren's dad magically appears as a spaceman, from the pages of a diary. How did we do that?
We dressed the actor up in the spaceman outfit and filmed his scenes in front of a big green screen.
He's ready to go - even if he's not REALLY in outer space!
Just look how many people are involved in the shoot - and that's BEFORE the special background is dropped into the scenes, to make it look like he's floating in space.
This is how it looks in the finished programme. Impressive stuff, eh?
