Playing With / Throw It In

Basic Trope: An actor improvises/screws up a line or scene, which eventually goes into the final product.
  • Straight: In a scene of Legend of the Ancient Trope, Daniel is supposed to tell Lord Evulz he is a dangerous fighter, then draw his sword. However, Daniel's actor draws the sword too quickly, and ends up flinging it offscreen. The director decides to keep it in, pretending it's a comedy scene.
  • Exaggerated: The entire movie is improvised by the actors.
  • Downplayed: Daniel is told to shout at Lord Evulz, "You damn monster!" However, the actor gets so in-character that he replaces "damn" with a harsher curse word. The director ends up using that take, deciding that the line is stronger the way he said it than in the original script.
  • Justified:
  • Inverted:
    • In a movie that is entirely improvised, Daniel's actor speaks a pre-written line that gets into the final cut.
    • The director suddenly tells the actors not to use a particular line from the script.
    • Before handing Daniel's actor the sword, the prop department put a lubricant on the sword, following instructions from the director, ensuring that he'll lose the sword even though it's not in his version of the script.
  • Subverted: The director says he'll keep it in, but a while later decides against it and orders a proper take of the scene.
  • Double Subverted: But he goes and puts the flub in anyway.
  • Parodied: Everywhere in the movie viewers can see microphones sticking out, No Budget special effects with strings and sticks, and some scenes are obvious bloopers. But the movie presents all them as parts of style, or even Stylistic Suck.
  • Zig Zagged: (continued from "Double Subverted") ...and then removes it when test audiences react negatively... But only from the theatrical release, because he puts it back in the Director's Cut version.
  • Averted: Daniel's actor thought of an idea to make the scene better, but refrains.
  • Enforced: Daniel's actor is told to improvise whatever feels right.
  • Lampshaded: "Wow, didn't expect that..."
  • Invoked: The story shows an actor improvising dialogue/behavior not originally in the script.
  • Exploited: Enforced Method Acting and Improv.
  • Defied: The director orders the scene to be shot properly.
  • Discussed: "Don't you think he could act more composed? Ah, well, everyone can make a mistake, and that would be a sight to remember."
  • Conversed: "Is it me, or it was a flub originally? Anyway, that's even funnier."
  • Implied: The characters are making a movie. One of the actors is famous for his ad-lib quirks.
  • Deconstructed: The audience does not like the thrown-in part and critics blame this moment for ruining the suspense.
  • Reconstructed: However, a little group of fans actually enjoyed it. Later, they manage to justify their opinion and infect as lot of people with it. Soon, the movie becomes Cult Classic.
  • Played for Laughs: "In the name of the Sun God, I shall banish thou and... pffftt... no, really, who needs all this cringe? I'll just kill you."
  • Played for Drama: "You did this again! I'm tired of your flubs! Get out of here! Let's find a better actor until it is not too late."

"Hey, that wasn't in the script! ...Ah well, Throw It In."
