The cast of the forthcoming 'Men in Black' spin-off continues to grow with big name stars, as Emma Thompson is the latest to join the likes of Chris Hemsworth and Tessa Thompson.

Thompson will reprise her role as Agent O, head of the secret MIB organisation, in the film which starts shooting in London in the coming weeks.

Other cast members include Liam Neeson, Kumail Naijani and Rafe Spall, so it's shaping up to be a pretty star-studded affair - and with 'Fate of the Furious' director F. Gary Gray on board, you can expect plenty of action, too.

Not a whole lot is known about the plot, apart from the fact that it will focus on new characters rather than Will Smith and Tommy Lee Jones's Kay and Jay - but with a release date pencilled in for next June, there's just under a year to go to find out.

The last 'Men in Black' film, 'Men in Black 3', was released in 2012.
