Yep… Hitting that magical B mark next weekend and if not by next weekend, it should definitely be the following week.
I hope Joker stays a solo film and doesn't do anything else. I can see greed taking over, but this actually the time to now expand and try this formula with other IPs. If some of those fail, then maybe come back for a sequel or related film, but I don't want WB to get single focused on this version of Joker, though.
And the whole profits sharing thing everyone is talking about is not as big of a deal as some are making it out to be.
Warner Bros co-finances all of their films if I'm not mistaken. Whether that's with 1 or 2 other production companies varies. In Joker's case, WB co-financed with two others and I think WB financed 50% of the film while the other two are split evenly (I think). This means WB only put up around $30 million~ for production, but they'll be reaping about 10-15x (and will likely be a little more than that by the end of Joker's run) that anyway with returns like these.
