Hollywood may be the Mecca to young acting hopefuls, but it isn’t where the movies are made. Films are shot in places as far afield as Australia, Czechoslovakia or Podunk, USA.

“Jaws” ostensibly took place on Long Island, but it was filmed in Martha’s Vineyard, Australia and the Universal backlot. “Legends of the Fall” was not Montana, but Calgary, Canada, and “Black Hawk Down” didn’t trek to Somalia but strafed Morocco instead.

To find out where some of those places are, the Travel Channel will present “Movie Lover’s Road Trip” on April 3, the beginning of a series of road trips which takes the viewer to places that really saw the action.

Angela Cartwright, who played Brigitta von Trapp in “The Sound of Music,” recently revisited Salzburg, Austria, where the classic was filmed. It’s featured in the show’s first episode.

“It was like stepping back into time. Nothing has changed. Heather Menzies-Urich (who played Louisa von Trapp) and I both went for the Travel Channel. We would stand there and feel like we were back in the movie. It was the most bizarre thing. It was like going back into your grammar school or something.”

David Brown, producer on Steven Spielberg’s second movie, “Jaws,” doesn’t have such cuddly recollections of that shoot.

“To get real shakes, we went to the Great Barrier Reef of Australia and found the sharks were too small. So the character which was played by Richard Dreyfuss, the character was in a diver’s suit so we didn’t have to send the actor down, so we got a midget to make the sharks look bigger.”

Stephen Furst, who played Flounder in “Animal House,” says the classic comedy was shot all around Eugene, Ore. Furst says they used two real fraternity houses next to each other for the celebrated frat house of the movie. “As extras we used real fraternity guys.”

“Animal House” filming is featured in the second episode.

Candy Clark, who played one of the teens in “American Graffiti,” reports that Mel’s Diner was an actual empty diner in San Francisco. That film is featured in the Travel Channel show’s first episode, too.

“It got knocked down right after we finished the film and turned into a parking lot, so with 20/20 hindsight, I bet they wished they hadn’t knocked it down — it would’ve been a tourist trap. But Mel’s picked up the ball, and they made a chain of Mel’s Drive-Ins.”
