Radio Advert - Deconstruction

I've decided to do some more  Radio Advert deconstructions so i can better understand more about what makes them memorable and effective. The advert is for the British theme park 'Alton Towers' and is advertising not only the park itself, but is also advertising available jobs for the company around the country. The Advert begins with the sound of a roller coaster, so you instantly know what the advert is about and you are clear on what to expect from the advert. Next you hear a familiar voice, and it sounds like they've managed to get the guy who does the voice over on 'The X-Factor' to voice the advert. This is a great coup, as his voice is known by almost everyone. When you hear his voice you always think that something big or important is about to happen and you instantly tune into the radio. The announcer continues to talk while the coaster goes along the track but is interrupted by his own screaming. He always says an important thing just before he shouts, so that it gets the attention of the listener at the most important points. For example he says 'We have a luxury Spar...' but goes over a scary part of the ride at this point and continues shouting the 'aaarrr!!'. This draws your attention to the spar, something you may know have known that Alton Towers have. Towards the end the ride stops, and the announcer speaks in his normal voice because he is now talking to potential employes of the company and must male it sound professional enough for people to consider it. His last line is 'I think I need to lie down for a bit.' Which implies that the ride was so good and extreme that it's warn him out, attracting all the thrill seekers in the audience to try the rides at Alton Towers.
I'm going to incorporate elements of this into my own radio advert in order to help it appeal to my audience, an example being the enthusiastic voice. Having a voice that is recognizable and distinct is very important, so I plan to use a voice that people will remember. Hopefully this will be effective and coax people in to want to view the film.
