Andy Serkis has revealed that one of the unexpected joys of playing Alfred in The Batman was being able to work with director Matt Reeves while "wearing a pair of trousers".

Serkis has become accustomed to performing for Reeves while wearing a motion-capture suit to play ape leader Caesar in Dawn of the Planet of the Apes and War for the Planet of the Apes.

The Batman is in IMAX and cinemas from 4 March, with IMAX previews from 3 March.
