How can I get a Keynote presentation to start a movie automatically

I want to use keynote to control a presentation that consists of three parts, including two movies of other keynote presentations.

Is there a way to have a movie start automatically when the slide is brought up?

My intention is to start an automatic keynote presentation that contains a couple of introductory slides that will change automatically followed by the automatic start of movie 1 then movie 2, all without interaction.

The alternative possibility may be to use the keynote versions of the two movies if there is a way to strt them automatically.

Thanks for any guidance.
