playing a movieclip in reverse

Hello,
I have a movie clip that unfurls text when the user does a mouse over and I would like to cover it back up when the mouse leaves. I currently have it "unfurling" with another movieclip just moving to right with a tween, revealing it gradually. I was thinking, when the user leaves the movie clip could I have the playhead in the timeline just backwards. Is this even possible or could I do the whole process with actioscript and make life easier?

Thanks
