HEY YOU! WHAT IF…
26 x 5 mins – comedy / factual / science
Have you ever wondered what would happen if the Earth was flat? Or if the moon was made of cheese or you could time travel?
Well, we’re not only going to tell you, we’re going to show you.
This is a bold, clever and mischievous factual series that plunges us into parallel worlds where anything can – and does – happen.
These are the ultimate thought experiments where the impossible is made real with photo-real special effects. But these films are not just amazing to watch – just like working out how a machine works by tinkering with it, they’ll reveal how our world actually works by messing with it. Even abstract principles like gravity, magnetism, light and sound will become highly visual.
Each short film in the series will ask a different question and take us on an unforgettable visual journey to find the answer – 'Hey You – What If?' is built to blow your mind, one question at a time.
26 Eps.
