Free Fire filmmaker Ben Wheatley has made a COVID-19 film in lockdown.The director said he took a fortnight between studio projects to make a film that he describes as “a response to the ongoing COVID-19 crisis”.Discussing the project with Little White Lies, Wheatley explained how he considers his projects according to the budget as well as the genre.“I’ve said it a lot, but I think I’ve always seen it as there being genres of subject but also genres of budget, and those genres of budget are micro-budget, low-budget, mid-budget, and high-budget, which make for totally different filmmaking experiences,” the filmmaker said.Wheatley went on to explain that he shot his coronavirus movie in 15 days in August, just before starting production on.
