Elmo: Portrait of a Serial Killer (2011)

Elmo plays rough with two foul mouthed movie goers. Hell raising kids show up to the movie and bash the plot line. Their mean spirited attempt to ruin the movie for all is met by Elmo's hammer of justice. The hammer turns out to be a knife and Elmo helps them see the error of their ways by slashing his way to their hearts...literally. Don't blink or you'll miss the best part of this spleen shattering, entrails ride of horror film. All shot in stop animation and real time puppeteering.
