The force is strong  ... in John Boyega's shorts judging from all the bumping and grinding he did at London's massive Notting Hill Carnival.

Boyega hit up the annual street carnival, along with some 2 million other people, and rode a carnival dancer - or two - like a 'Star Wars' landspeeder ... or Dewback ... or Luggabeast. 'Star Wars' fans get the picture. Actually, everybody understands.

'Star Wars VIII' wrapped filming in July, but looks like John's still wielding a lightsaber.
