Dreamworld's 120m high Giant Drop - which has been listed in the Guinness World Records as the "tallest, vertical free-fall ride in the world - is one of only eight white knuckle rides selected for a 30-minute US TV program, Extreme Terror Rides 2.

The seven other extreme rides featured on the show, which aired in the US earlier this month on the Travel Channel, were all from parks in the United States.

The listing follows the ranking of Dreamworld's Tower of Terror among the Top 6 World's Scariest Rides by Canada's Global News in August.

Both acknowledgements are a boost for Dreamworld and for Queensland tourism said Dreamworld CEO Noel Dempsey.

"We've been saying for years that Dreamworld has some of the tallest, fastest rides in the world and it's great to see that endorsed by the international media."

Mr Dempsey added that the news comes just as Dreamworld is about to launch a new television advertising campaign d based on rider reaction to the Big 6 Thrill rides and called Man Up.

Kicking off in South East Queensland on September 13, the cheeky campaign typecasts six different screams heard on the thrill rides including The Suddenly Religious (Oh my God!), the Eye Clenchers (I can't look) and The Brown Panters (Agh Aghhhh!).

"This advertising campaign is about resonating with teens. The Big 6 (Thrill Rides) is not meant to be achievable for everyone. And just because you can ride one of the Big 6, doesn't mean you can do them all," he said.

"We're telling the teens to 'man up' and throwing them the challenge. If you haven't been here for a while, then come back and check us out. There's no need to go offshore to get the best in the world."

Megan Stalley, a Dreamworld marketing executive and one of the team who worked on the campaign said the aim of the new advertisement was to put a personality behind the Big 6.

"Everyone screams on a Big 6 thrill ride, no matter who they are," Stalley explained. "The funny thing is some (screams) penetrate through to our offices. They stop us from the phone call we are making or the email we are typing. We've heard all the screams and this campaign is based on those that we hear over and over again."

"What we are saying is that you will scream on a Big 6 thrill ride, but you are going to want to do it again... maybe except for the Giant Drop."
