In an interview with IGN, Trevorrow said he wouldn't have used a scene of Chris Pratt's character Owen riding a bike alongside velociraptors in the trailers.
"There really is a natural bit of conflict between a film maker wanting an audience to be brought slowly into a film and be eased into accepting an image like that, and so if in the first trailer if you've got something [like that], that is bananas, that's bonkers.
"In my opinion, I think they have shown far more of this movie than I ever would have wanted."
He says it's more important for a movie to build up the trust with an audience so they are more willing to accept bold ideas, such as the genetically-spliced main dinosaur or the motorbike scene.
Trevorrow also joked that he emailed the marketing people asking them to stop spoiling everything.
"Can I just have the credits, can you not spoil the credits - at least give me that," he said.
The director agreed with the interviewer that the trailers made the movie appear more action-oriented than it really was.
"This kind of marketing ... has historically been able to get a lot of people into theatres ... I trust that a lot of people seeing the movie will be calling their friends and saying, 'It's not like [the trailer] at all, it feels much more like Jurassic Park than we thought it would, even though those things are in the movie'."
The film's marketing campaign has been criticised in the past. The movie's first clip was slammed by Joss Whedon as sexist, which put the movie and leading heroine Claire (Bryce Dallas Howard) under intense scrutiny.
