Martin Scorsese has added Ethan Suplee and Katarina Cas (pictured below) to the cast of "The Wolf of Wall Street," an upcoming film about a stockbroker's rapid ascent and ignominious fall.
Scorsese is directing the film, which is based on Jordan Belfort's memoir and stars Leonardo DiCaprio, Jonah Hill, Jean Dujardin, Rob Reiner, Kyle Chandler, Jon Favreau and many more.
Shooting on the film begins next month in New York.

Suplee, whose credits include "American History X" and "Remember the Titans," will play Chris Knight, a fellow trader. Cas, who was just in "The Guard," will play Carolyn.
"Boardwalk Empire" creator Terence Winter adapted the memoir, whose rights are owned by Red Granite Pictures. Red Granite's Riza Aziz and Joey McFarland are producing with DiCaprio, Scorsese, Emma Koskoff and Alexandra Milchan.
