The original The Nut Job began with £667,000 in August 2014.
The partners may now have wished they had quit while they were ahead, at least going by the UK result for The Nut Job 2: Nutty By Nature.
The Emoji Movie is also performing well, and Captain Underpants and Cars 3 are both right behind The Nut Job 2 in the UK chart.
Presumably, the animated title was created for an attractive price, making the £4.5m UK final gross for The Nut Job a profitable proposition for Warners.
