With James Wan’s Aquaman currently in the middle of some additional photography, the Jason Momoa-starrer has added Randall Park to its ranks.

Park is best known for the likes of Veep and The Interview, and he’ll be playing Dr Stephen Shin in the picture. Director Wan took to social media to confirm the casting:

So happy and fortunate to be finally working with this man, @parkrandall, on pickups. #DrShin pic.twitter.com/q95PFEUSC2

The Dr Shin character is a longtime mentor figure of sorts for Aquaman, in the comic books helping the young Marine Marvel to understand his unique abilities. In addition to being a marine biologist, Doc Shin is also pretty well versed in all things Atlantis.

Continuing Warner Brothers’ DC Extended Universe, Aquaman is currently set to swim to the silver screen on December 21st.
