That's very good for Jack Reacher, Trolls did very well as well even excluding previews, Trolls and Storks will benefit from half term.
It'll be interesting how Doctor Strange does, it has a Tuesday opening so I'm thinking £7-8m for the six day opening, Thor: The Dark World did £8.65m three years ago with a five day opening but that was a sequel. Ant-Man did over £5m and Guardians did over £6m on its opening.
