Hinckley cinema in danger of closing.
London-listed company, which operates 751 sites in 10 countries, has run up debts of more than £4bn.
Like other cinema chains, Cineworld was hit hard by the pandemic.
Cineworld recently said post-Covid customers levels were lower than expected and blamed “limited” film releases.
On Wednesday, the chain said its business operations were expected to remain unaffected by its move to seek financial stability and that it “expects to continue to meet its ongoing business counterparty obligations”.
