Henry Cavill says he wanted to make the jump himself as well, but Tom Cruise shut down the idea because Cavill hadn’t been through the necessary training.
Tom Cruise is famous for his willingness, and his desire, to do all his own stunts.
While Mission: Impossible – Fallout made a point to play up Tom Cruise’s HALO jump in the new film, he’s the only actor involved in that particular stunt, even though he’s not the only one in the scene.
However, apparently, the actor has no problem shutting down other actors from doing the same when necessary.
