Warner Bros. has picked up an untitled pitch for a fantasy set in Central Park. Bryan Schulz and Neil Uliano are planned to write the script, according to Variety.

The story follows two brothers who, while visiting their grandfather in Gotham, meet a man who shows them a mystical realm in Central Park that is in danger.

The idea for the fantasy was hatched by WB senior veep Jon Berg.

WB and Lin have already laid the groundwork for the project by aligning with the Central Park Conservancy, which cares for the park, but no production date has been set.
