Bruno begins developing contempt for the teenage star of the movie, Jordie Jones, especially because the girls at Miss Scrimmage's Finishing School go crazy about him.

Feeling sorry for him, Bruno cancels the fireworks prank and decide to throw him a birthday party the next night, while Boots sleeps in Jordie's trailer to fool security.

Miss Scrimmage, Dinkman, and Jordie’s overprotective manager Goose Golden become very upset about the incident, so Mrs. Sturgeon decides to invite them over for dinner so they can settle their differences.

The day before the camping trip, Bruno makes one last attempt to sneak into the movie when he gets Boots to successfully divert the stuntman that was supposed to shoot that scene.

Bruno, disguised as the stuntman, successfully performs the stunt, but he gets rejected after his wig falls off and Dinkman discovers his true identity.

Bruno and the boys go off to the camping trip, but to their surprise, Jordie sneaks along due to him feeling imprisoned by the never-ending requests to do interviews.

Despite being told by Dinkman to keep it a secret, he accidentally spills it, resulting in the school turning into a media circus as hundreds of news reporters settle at the campus, demanding answers.

However, they connect the wrong wires, and end up setting off a firework that Bruno forgot to dismantle after cancelling the plan to prank Jordie earlier in the novel.

Meanwhile, the stuntman who was supposed to do the bicycle stunt ends up injuring himself trying to escape the trailer, thus resulting in Bruno achieving his dream of finally being part of the movie.

Publishers Weekly referred to Macdonald Hall Goes Hollywood as a "rollicking tale" and highlighted "Korman's vibrant dialogue and breakneck action".

[1] On behalf of the Canadian Review of Materials, Ila D. Scott similarly called the characters "only briefly sketched" but noted that they "are consistent and enjoyable".

[2] Scott further wrote, "Korman shows his strength with this particular kind of novel in his fastmoving pace, his comic touch with dialogue, and his understanding of what makes boys this age tick".

[2] Kirkus Reviews concluded, "The charm of Korman's latest 'Bruno & Boots' story lies in his ability to make the total chaos of slapstick comedy utterly believable.
