Check out a pic of Henry Cavill training with Roger Gracie in Brazilian Jiu-Jitsu.
It's unknown if Cavill is training for a role in a new movie, but Cavill posted the pic on Facebook with:
Getting schooled by Mr. Roger Gracie. An honour and good fun! #BJJ Roger Gracie @RogerGracie

I train in Jujutsu myself, but a different school: Danzan Ryu Jujitsu (Hawaiian).
Henry Cavill next stars in Justice League, which is currently filming in the UK.
