Insert movie clip in game

Hello flashgame coders!
I am still a beginner at Flash and i’m trying to program a very simple game. I can do a little Action Script (i’m a java programmer) and i know how to make tweens and other animations using the timeline.

Now i would like to combine the two. You know how with adventure-games there would be a video sequences the player would just have to sit trough, say after making some discovery?
I would like to do this in flash: certain user actions prompt a movie clip to start and then the user can only continue after the animation has ended.

Any pointers on how i do this?
Much appreciated!
