From the back cover:
Michael Harlan (John Stockwell) has procrastinated on his science project until the last minute, and his teacher (Dennis Hopper) issues him an ultimatum: turn in a science project or flunk. So Mike scavenges a military base's junk pile for a suitable gizmo to pass off as his project. He finds one... and unwittingly unleashes the awesome power and energy of the unknown. Twisted dinosaurs. Time warps. A fantastic realm where the past, present and future collide in a whirling vortex that takes the class on a startling adventure back in time and into the future.

Fisher, on his role in My Science Project:
"Forget the danger, think of the fun."

"When I say those lines," said Fisher Stevens, who stars as a high school student whose best friend's science project brings them crashing through the frontiers of time and space, "I'm really cooking. It sets the mood for what's to follow. And what follows is terrific!"

As Vince Latello, the street-smart displaced Brooklyn kid in My Science Project, Fisher, who weighs in at 130 and is five feet eight, says he was very shocked that he got the part. "When I read the script, I didn't see myself as Vinnie." I thought the role of Sherman, the nerd, was more in keeping with my past roles," he confessed. "But I just love it. Any breakout from previous characterizations is terrific."

Being in character nearly got Fisher in serious trouble during the filming. As he tells it, he was on his way home from the studio one evening when, as he was entering his apartment complex, a couple of kids stopped him. "I was in character. Singing and just having a good time. When all of a sudden these kids attacked me. I was being mugged. I said, 'Get out of here,' just like Vinnie would have. Then one of them slashed at me with a broken bottle and cut my arm. They were punks. They ran away but the police caught up with them."

Fisher said that he made up an entire backgroud for his film character since movies are so different from plays that an actor has to create his chacter's personal history. "You have to make it up," he said, "as opposed to the theatre where there is more detail in the script about the character."
