You may remember John Cho as Harold in the hilarious stoner comedy series “Harold and Kumar.”  He’s also portrayed Sulu in the rebooted “Star Trek” film franchise.  His latest work may be his darkest yet, as he portrays a scared parent of a possessed child in the second season of “Exorcist” on Fox this fall.

Lots of laughs with John Cho below, as he explains how he can navigate low-brow humor and high-concept horror.
