18 WTF Moments From 2017's Summer Blockbusters

9. The Rihanna Scene - Valerian & The City Of A Thousand Planets

Talking of celebrity cameos, here's one that actually had some effort put into it, with the end result proving delightfully bonkers.

When Valerian (Dane DeHaan) attempts to track down a missing Laureline (Cara Delevingne), he ends up in a sex club run by a sketchy pimp, Jolly (an hilarious Ethan Hawke).

Here he meets Bubble (Rihanna), a beautiful shape-shifting dancer who performs an incredible show for Valerian, switching outfits numerous times with her magical abilities.

It's a Hell of a scene, and that's really just the beginning. From here, Bubble is convinced to help Valerian on his quest, revealing her true form as a blue, blob-like creature, before later dying while attempting to flee some trigger-happy aliens.

Say what you will about Luc Besson's wildly over-budgeted sci-fi epic, but it's like nothing else out there, and this scene was absurdly entertaining.
