In what may simply be a loving tribute to one of the most popular shows on TV or a very subtle commentary on Jay Leno's last episode as host of The Tonight Show, Conan O'Brien got in full zombie makeup Thursday night to commemorate the premiere of the second half The Walking Dead's fourth season on AMC.

Check out the Conan video, which led into an interview with TWD cast members including Andrew Lincoln, Norman Reedus, Danai Gurira, Lauren Cohan, Steven Yeun and Melissa McBride, after the jump.

 

 

The Walking Dead, which features makeup effects by Greg Nicotero, returns to AMC this Sunday with the episode "After."
