I'm Mary Poppins y'all

In the next film can every character just be played by Fassbender?

Pretty absurd premise, but good for a "one guy shoots his way through hundreds of people" action flick. Just realized it is the sequel to Olympus Has Fallen. Both are about the same amount of stupid and the same amount of entertaining.

I know this is supposed to be really shocking, but I thought it was pretty mild and kind of boring.
