A lecture at the University of South Florida just went from Orange to Strange.

David Harbour, aka Chief Jim Hopper from Netflix’s “Stranger Things” will be hosting a free lecture at USF on November 20, in replacement for Emmy-winning "Orange Is The New Black" actor Laverne Cox, who had to cancel due to filming conflicts.

So far, details on exactly what Harbour will be speaking about have not been released. We’re willing to bet their won’t be any "Stranger Things" spoilers, but who knows?

The lecture takes place at the Marshall Student Center Oval Theater, doors open for the event at 7:30 p.m. and it will begin at 8 p.m. Seating is first-come, first-served, with lines forming at 5:30 p.m. and the only ones allowed to RSVP are USF students.
