Wondering what a William Petersen-less CSI will look like? Well, here’s your chance to see how Morpheus might shake things up.

Later this week, The Matrix‘s Laurence Fishburne will join the CBS hit as Dr. Raymond Langston, the man who’ll eventually become a part of the investigative unit. The Oscar-nominee will play a former pathologist who aims to understand criminal behavior. According to the network, Langston wants to know “how and why people commit acts of violence—tendencies he disturbingly sees within himself.”

Look for Fishburne’s first appearance this Thursday, December 11.
