Friday the 13th. Under Siege. Piranha. What do these movies have in common? They are all "knock-offs" of hit films. On Knock It Off, hosts Sam, John and Kirk dig into the art and history of popular films and their less popular imitators. Were these “knock-offs” able to catch lightning in a bottle again or did they end up cheap imitations? Will Sam, Kirk, and John be able to stay focused and sound smart or will they get derailed by endless bits and mediocre impersonations? So many questions, tune in for answers!
