What is the 90s movies name with kids watching a dinosaur rock cartoon in the beginning?
I’d say it’s “Adventures in Dinosaur City” (1992). Adventures in Dinosaur City opens up in the suburban home of Timmy Shepherd, a teenager whose parents are eccentric research scientists. We see him with his friends Jamie and Mick listening to Jamie read them a story about dinosaurs she has written. They don’t like her writing, but they do like watching the new animated dinosaur cartoon Timmy has just acquired. Meanwhile, Timmy’s parents have just completed work on an interdimensional travel device, and have it activated in their lab in an adjacent building. When they must suddenly leave to attend a physics conference, Timmy is left alone, and he takes his friends back into his parent’s lab to watch the dinosaur cartoon. Timmy turns on the video not knowing that the transporter is also activated by the same remote control. Suddenly the three are sent through interdimensional travel to another world which appears to be a real life version of the dinosaur cartoon.
