DC Extended Universe producer Charles Roven previously stated that Justice League: Part 1 is gearing up to begin filming “in the first or second quarter” of this year, with production also slated to take place primarily on sound stages in the UK. The project now has an official April 11th, 2016 filming start date, further demonstrating that WB/DC ultimately expects Batman V Superman to perform well enough – in terms of both the general reception and box office performance alike – to justify further continuation of Snyder’s vision for the Justice League cinematic universe.
