Diana Lee Inosanto played Morgan Elspeth in Chapter 13 of The Mandalorian – The Jedi.
Insonanto has acted in a handful of roles (the earliest credit I could find for her was a Blue Moon Employee in the series Moonlighting in 1986-1987) but she is more well known for her career in stunts. She was a stunt double in the TV series Walker, Texas Ranger and Buffy the Vampire Slayer as well as the film Star Trek: Enterprise.
More recently Inosanto was the martial arts trainer for Melissa McCarthy in the 2015 film Spy and the trainer for Rosa Salazar in the 2019 film Alita: Battle Angel. Inosanto also wrote, directed, produced, and starred in the 2008 film The Sensei.
Her godfather was martial arts legend, Bruce Lee.
