Six films to watch this week

Claire Foy and Richard E Grant in raucous period satire ‘Savage House’; Charli XCX adds charisma to ‘Erupcja’; He-Man struggles for heroism in ‘Masters of the Universe’; ‘Acting’ illuminates the art of performance; ‘Backrooms’ is a deadpan horror directed by a YouTuber; Dustin Hoffman and Leo Woodall strike gold in crime caper ‘Tuner’.
