Movie sequels are built on the notion of brand identity, of reuniting audiences with the familiar elements that made the previous movie(s) a hit, and arguably no original element is more important than getting the cast back for another go-around.
In the case of these 10 movies, however, a previous star - be they the protagonist or a crucial supporting cast member - will be conspicuously absent, as confirmed by either themselves or the studio.
In some cases the actors didn't feel like it was a worthwhile role, yet elsewhere a few performers were rocked by career-threatening PR scandals which made their returns untenable, and in other cases there's just not much rhyme or reason to their exclusion at all.
It of course remains to be seen how these absent performers will affect their respective franchise sequels - and in some cases it's clearly not a bad thing at all - but in each instance it should ensure that the new sequel is quite different from the movie that preceded it...
