Famed sibling dancing duo Les Twins have joined the upcoming Men in Black spinoff film directed by F. Gary Gray.

The brothers, whose real names are  Laurent Nicolas Bourgeois and Larry Nicolas Bourgeois, join the Tessa Thompson and Chris Hemsworth-toplined film, which also stars  Liam Hemsworth, Kumail Nanjiani and Rafe Spall.

Character details are unknown.

Sony is targeting the now-untitled film for May 17, 2019.

Both Will Smith and Tommy Lee Jones are expected not to reprise their roles in the  “contemporary sci-fi pic about the black-clad secret force that protects Earth from the alien scum of the universe, focusing on new characters chasing villains that put the picture on more of a global scale than the two previous films.”

Walter F. Parkes and Laurie MacDonald are producing the spinoff film, and Steven Spielberg is executive producer. Matt Holloway and Art Marcum are the writers.

This project initially came as a surprise, as it was anticipated that the next MIB film would be a mash-up with Sony’s 21 Jump Street franchise. This spinoff is being fast-tracked ahead of that project, which is probably dead.

Known initially for their YouTube street dancing videos, Les Twins got their first big break on Cirque du Soleil’s Michael Jackson: The Immortal World Tour. They are most known for being the only men dancing with Beyoncé on the Mrs. Carter Show World Tour. They also joined Beyoncé and Jay-Z on the On the Run Tour. In 2016, they won Jennifer Lopez’s World of Dance. 

THR first reported the news.
