You might recall how last weekend's episode of Saturday Night Live had musical guest Billie Eilish.

Billie stunned the SNL audience and viewers at home with her performance of 'Bad Guy'.

It wasn't just the song that impressed though - it was the cool camera effects that made the pop singer appear to be climbing all over the walls.

It was a pretty creepy effect that suited the sinister nature of the song. Many compared the camerawork to similar examples in movies like 'Inception' and '2001: A Space Odyssey'.

You can watch it here if you missed it.

SNL has now released a video on how the effect was accomplished as Billie Eilish brought SNL through what she wanted the performance to entail.
