According to The Batman Brasil a source on the film production team told them the following concerning Rob and Matt Reeves’ The Batman:

• Rob will return to the set on 2 January 2021 and will finish filming in late January/early February 2021, Colin Farrell on 7 February 2021 and Zoe Kravitz on 7 January 2021. Andy Serkis and Paul Dano have finished filming.
• the film is already in the process of reshoots, as it has already been recorded 100% of the film. He will return to record some scenes in June, only in case of urgency.
• if all goes according to plan, we will have a big surprise soon from Matt Reeves.
• Reeves really wanted to release this film in November. But Warner and Robert Pattinson didn’t like it, and preferred to leave it until 2022.

We hope this information is correct, would love to see the big surprise sooner rather than later. In any event, we can now say – The Batman is coming next year (always looking for the silver lining).

Thanks The Batman Brasil.
