Paramount spent somewhat less money on Ghost Protocol,
the fourth Mission Impossible
film, than they did on the third and made a great deal more money with a slightly higher percentage of it coming from the foreign markets. In fact the foreign percentage rose some with every MI film.
On the third one, they didn't even make back their production cost on the domestic release.
They're so anxious to do a fifth that Cruise just dropped out of Warner Bros The Man From Uncle
because production on MI 5 has been moved forward.
