The Crystal Maze US Production for @Nickelodeon Is Underway (We Think)

We've got no idea what 'Day 1.' entails but all indicators point to production having started. We knew it would be the end of August based on a job listing that was dated around now and this picture has popped up on a social media feed (anyone know what app it's from? EDIT: found it, Instagram story)

ID removed in case she/he shouldn't be posting

Now 'Day 1' does not strictly mean Day 1 of filming, it can simply mean today is the first day of work on set, perhaps even just for that person posting it, Day 1 for anyone touching up the paintwork is earlier than Day 1 for anyone vision mixing for example. Today could be a rehearsal day, or like when we were there in March camera blocking, where they worked out what angles would be best for each game. It was a day on set but it wasn't a filming day, not properly anyway (and if that footage all still exists, can we have it well hidden please). Could be the case that today they introduce the new host to everyone, let him or her have a run-through ready for filming so it can all go smoothly and to schedule when they have new contestants on set.

Of course, it could also actually mean Day 1 of filming, negating everything I just said, but all we know for certain is there are people on set and the lights are on. Either way, things are happening.
