Room of requirement.

"Peter Stormare Gives Update on ‘Constantine 2’; Keanu Reeves Reportedly Unhappy with Script" by Meagan Navarro (very similar articles seen on a number of other entertainment news sites).

"'But to do a sequel, the studios want to have, you know, cars flying in the air. They want to have people doing flip-flops and fighting action scenes,' Stormare said."

I think I agree with Keanu. We already have the John Wick franchise. IT IS AWESOME. But we don't need the Keanu-as-Constantine franchise to turn into another John Wick franchise.

I hope they resolve this soon because I am DROOLING at the chance to see Stormare play Lucifer again.
