Christopher Nolan's latest film, The Odyssey, is already making headlines. Shot entirely with IMAX 70mm cameras, it’s got a star-studded cast including Zendaya, Tom Holland, Robert Pattinson and Lupita Nyong'o. The epic has also had a huge box office opening, earning nearly $260 million worldwide - that makes it one of the year's biggest releases so far.

But not everyone is celebrating. From casting choices to its portrayal of Greek mythology, the film has sparked debate and criticism online. We speak to BBC Culture's Nicholas Barber to break down the controversy and explain why so many people are talking about it.

A monkey with striking orange lips and a black furry coat has been officially recognised as a new species in the Democratic Republic of the Congo. It was first spotted back in 2008, but at the time researchers only managed to capture a blurry photograph, leaving many questions unanswered. Years later, after extensive fieldwork and research, scientists have finally confirmed it as a species new to science. They've named it “Colobus congoensis”, while local communities have long known it as “Likweli”.

Our BBC Science Correspondent Victoria Gill reveals what makes this monkey so special and how researchers finally solved the mystery of its identity.
