Why this premise still a thing that people think is a good idea? A comedic actor reaches a certain level of notoriety that, in order to make bank on their presence on-screen, someone decides that the best way to go is to make more of the actor to spread around, i.e. double-casting. It’s essentially the textbook example of ‘too much of a good thing’, and what makes it worse is that it is rarely if ever implemented by comedians who are tolerable all on their own, let alone in multitudes.
Eddie Murphy did it with
the Nutty Professor movies (first one was alright, but c'mon, The Klumps was pretty dire stuff), Adam Sandler infamously tried it in Jack &
Jill, and the whole enterprise has become such a cliché that it even made for
one of Tropic Thunder’s gag trailers. It’s an idea that shouldn’t exist in a
modern release to begin with, so you can imagine how well it turns out in the
hands of perennial shite script magnet Marlon Wayans.
