Whooop!

Apparently Riddick 4 is currently in active development!

I've long felt that #Riddick is the last great B-movie series. It always looked kinda cheap and was quite hammy, but it always felt earnest and sincere. It always is confident in its own coolness and does not have to make ironic jokes to apologize to the audience for being silly.
Which is just something you rarely see anymore in fantastical action movies.

4 movies over 24 years is a good pace for these.
