J.J. Abrams ain't gonna like this ... 'cause Harrison Ford put his recently broken leg at risk this week when he went barreling down a 2,500 foot mega-slide -- just days before he's due back on the "Star Wars" set.
Ford -- whose Han Solo scenes were pushed back when he broke his leg on the set in June -- hit up the Alpine Slide in Jackson Hole, Wyoming Tuesday to take the 2,500 foot plunge with his family.
The slide is no joke -- with riders sometimes reaching speeds of 30 miles per hour. And we're told Ford was FLYING down the chute ... and screaming to the rider in front of him to speed up!!!
We're told Harrison is a regular on the Alpine Slide -- and often rides with his grandkids -- but when you're nursing a broken ankle (and you're 72) and an entire production revolves around YOU, maybe find a less dangerous hobby??
Fortunately, the force was strong with Harrison -- no injuries, no accidents, no problems. He's reportedly due back on the "Star Wars" set by the end of the month to finish shooting.
