Looks like we may have some idea of when Todd Philips' standalone Joker movie is scheduled to begin shooting.
The Tracking Board's Jeff Sneider shared what appears to be part of a larger press release of some sort, which reveals the project's logline and lists a start date of May 1, 2018. We recently found out that Joaquin Phoenix was in talks for the lead role of the Clown Prince of Crime, and this also reveals his status as "interested".
So, can we trust this information? Well, Sneider is usually a reliable source but even he cautions that the details are subject to change. He also seems to have posted this during a little Twitter rant, so we should probably take it with a pinch of salt until we learn more.
