Wait... no... why?
Seriously why does Hollywood keep doing this? What happened to 3 and done? Next thing you know they'll be making a Back to the Future IV w/o Michael J. Fox... it'll be the adventures of Biff or something.
There's a rumored
Jurassic Park IV...
Terminator IV...
Tremors IV happened
Rocky VI happened
there's others too, and now a 65 year old Harrison Ford is going to reprise his role as Indiana Jones? No, stop it!
