Carey in the music video of "Fantasy", riding a roller coaster.

The single's music video was the first that Carey directed entirely on her own. Carey had been open about the fact that she had not been happy with some of her previous music videos. She therefore decided to single handedly direct the video, so the outcome would to to her exact choosing. Carey said her inspiration for the video was to give off a "free and open feeling," trying to portray the freedom she had finally achieved in being allowed to direct her first video. The video for "Fantasy" debuted on September 7, at the "MTV Video Music Awards". The video begins with Carey exploring the
Playland Amusement Park (

The video continues showing snippets of Carey at the park, until the end of the second verse. Afterwards, Carey proceeds to an outdoor celebration that involves people dancing atop their cars.
I'd done a lot of videos and wasn't always a hundred percent thrilled. For the most part, I was never thrilled with the results, so I figured I would give directing a shot. It was a pretty simple concept. Most of the scenes were featured at the amusement park, at a late-night outdoor celebration. I was really happy to be able to include O.D.B in the remix video.
