Jacob D is an actor in Jurassic Shark, in which he played Billy Trenton and Kyle Blakes. He returned to play Billy in Jurassic Shark II: The Retribution, and may reprise the role a third time in Jurassic Shark III: The Revolution. However, this is currently a rumor, as the character was killed in the second film.
Jacob's first film was Island of Doom: Jurassic Park, although he did not appear in the finished portion due to its cancellation and instead appeared in a short video featuring some of the film's outtakes. Long before the film's completion, Jacob was confirmed to be in a new film, titled Jurassic Shark , in which he starred as Billy Trenton and Kyle Blakes. Jacob aided Starscream7 in adding details on the external and internal parts of the shark.
However, as production of Jurassic Shark continued and filming began, Jacob was greatly absent and caused many troubles for the crew, and this annoyed everyone to the point that Billy barely appeared for five minutes in the entire movie, despite the various attempts to keep his character at large. Yet near the end of the summer, Jacob suddenly returned to participate in filming, completing several scenes, although he didn't appear as much as he was meant to. Through several debates, Starscream7 came to the conclusion that Jacob would be reprising the role in Jurassic Shark II: The Retribution, although the role was minor. He is rumored to be returning for the third and final film, Jurassic Shark III: The Revolution.
