Some comedians stand in front of a microphone and "recite" their jokes to an audience - that's just NOT Mark Knope's style at all! His voice inflections and well-thought-out body movements onstage help "tell-the-story" for his audiences...
Mark has been writing, directing and "acting-out" his comedy performances for many years - it's only natural that he'd be able to adapt himself to performing in front of a camera (at someone else's direction!)
QUIET on the set...ROLLING...SPEED...SCENE one/TAKE one...annnnd ACTION!
