Madame Web has registered one of the weakest box office opening weeks of all time for a film based on a Marvel character.The film was released into cinemas around the world on February 14, and in its first six days, it took just $26.2 million (£20.8 million) in the US, and a further $25.7 million (£20.4 million) internationally. This represents an underperformance, even compared to Sony’s recent Morbius, which itself was seen as a commercial disappointment.Based on the Marvel Comics character of the same name, Madame Web stars Dakota Johnson in the lead role as a woman who develops psychic abilities.
