Of course it's not essential, and usually after three, if not even by two, sequels go downhill. I guess for me this is probably the only trilogy that I can't choose which one I like best. It'll probably be just as well to leave it at three, but money talks and this film was such a success, I think at some point there will be a 4th. Whether or not it'll continue to be successful, who knows.

I can see Universal trying to continue on without Greengrass and Damon, and perhaps even as a new DTV franchise.
