Either something has gone wrong on the "Jurassic World" set, or everyone is pretty much going according to plan.

Those are the two possibilities you have to consider when director Colin Trevorrow posts a picture to Twitter of a bloody handprint on the side of a veterinary trailer.

This being the fourth movie in the "Jurassic Park" series, I have to assume that the handprint is meant to be there because of some dino-related accident, as opposed to a real-life onset one, because that would be very uncool and probably not appropriate for a TwitPic.

But bad news in the world of "Jurassic World" is good news for us because we'll be the ones who get to enjoy the dinosaur chaos when the new movie starring Chris Pratt and Bryce Dallas Howard hits theaters on June 12, 2015.
