This week marks the 20th anniversary of the classic film, Jurassic Park. Michael Dhar, a science writer and contributor to the website Live Science, tells Melissa Block and Audie Cornish about how the science featured in the movie holds up to what we know about dinosaurs today.


From NPR News, this is ALL THINGS CONSIDERED. I'm Audie Cornish.


And I'm Melissa Block.

Twenty years ago this week, this megamovie roared into theaters.


BLOCK: "Jurassic Park," the 1993 film, brought dinosaurs to life in a way that had never been done before.


CORNISH: Yup. That's one scary tyrannosaurus.

MICHAEL DHAR: I think I was 13 when that movie came out, so it has played a big part in my childhood and my life.

CORNISH: That's Michael Dhar. He writes for As a fan, he wrote an article comparing what we know of dinosaurs today with the science featured in that movie two decades ago.

BLOCK: Let's take the movie version of T-rex.


RICHARD ATTENBOROUGH: (as John Hammond) Well, we clocked the T-rex at 32 miles an hour.

LAURA DERN: (as Dr. Ellie Sattler) You said you've got a T-rex?

ATTENBOROUGH: (as John Hammond) Uh-huh.

SAM NEILL: (as Dr. Alan Grant) Say again?

ATTENBOROUGH: (as John Hammond) We have a T-rex.

BLOCK: In the movie, the T-rex chased after cars and ate people, but Dhar says not so.

DHAR: The T-rex in the film was portrayed as this hunter who goes after big prey, but the evidence shows that the T-rex operated more like a scavenger. So he would have looked for prey that was already dead. He wouldn't have run very fast.

BLOCK: More recent science suggests dinosaurs would also have looked quite different. They were more colorful and...

DHAR: It's probable that if you were actually to go back in time and look at the T-rex, it would be, no, maybe kind of cute. It would have a lot of plumage and feathers.

CORNISH: Cute? Bright plumage and feathers? What?


BLOCK: So maybe they would have been less of that and more of this.


CARROLL SPINNEY: (as Big Bird) And now, a poem by Big Bird. That's me.

CORNISH: T-rex was more like a Big Bird according to Michael Dhar at LiveScience, but could that work in a dinosaur movie?

DHAR: I guess you can make anything scary. Big Bird with teeth might be a little frightening as well.

BLOCK: I don't know, Audie. Big Bird's definitely not as scary.
