Slow down movie clip

Hi guys,

I have this movieclip of a dice which has 6 frames and a different dice face on each frame. What I am wanting to do is gradually slow down the frame rate of this movieclip over a period of time until it eventually stops.

I know you can’t actually adjust the frame rate of a specific movie clip but I was wondering if there is some kind of work around using ActionScript.

Thanks for your help.
