Per TV Line , Ivanek will play "Brett Forsythe", a businessman who specializes in hostile corporate takeovers and is an avid collector of valuable artifacts from natural history.
Forsythe lands in the FBI’s crosshairs when he is suspected of orchestrated a “dino-mite” heist — that is, the theft of a Tyrannosaurus Rex fossil and its egg, which together are worth millions.
In addition, Hazlewood has been cast as "Dr. Reva Khatri", a curator at the targeted natural history museum. A passionate paleontologist, Dr. Khatri believes the true value of dinosaur fossils comes from sharing them with the world.
Expect for the two actors to appear in episode 8.
