Cert 12 Stars 4

Sylvester Stallone and Dolph Lundgren return to reignite the Cold War as they face off once more in a typically two-fisted and enjoyably bruising bout from Sly’s ‘Rocky’ boxing franchise.

A loose retelling of Rocky 4, the former fighters are now the trainers of the younger generation, which sees Michael B. Jordan’s world heavyweight champ take on the son of the Russian who killed his dad.

It scored a knockout £160m worldwide on a puny £40m budget due to the strong character work and screen history that gives emotional weight to the heavy punching.
