Writer/director Edgar Wright has revealed that Pinewood Studios is too full to accommodate his long-awaited production.
"Ironically, Ant-Man was meant to shoot in London, but London is full because I guess that Pinewood extension got turned down," he told Screen Daily.
"While the tax break is good for Hollywood films shooting here, it's probably not that great for British films shooting in the UK.
"Some middle-to-low budget films are going to find themselves without crew because all the American films are shooting here."
Pinewood's application to add 15 new studios was rejected by the local council in May.
Wright has promised that Ant-Man will surprise people.
The film is yet to announce any castings, but Joseph Gordon-Levitt and Paul Rudd are believed to be in the running for the lead role starring alongside Rashida Jones.
