movie chain question

[Kenneth ken]

In the movie chain game is the goal to simply make as many posts as possible until every one gets tired of playing?

Or

Is it to link as many actors-movies-actors as possible without using the original actor again?

The latest movie game thread started with
Renee Zellweger - Bridget Jones' Diary - Hugh Grant

The game went quite a while before her name came up again, but it went right on as though she wasn't the first actor named.
