“Due to geopolitical divides, countries are having second thoughts about non-proliferation or their non-proliferation obligations, in the sense that many countries were relying or are still relying on nuclear umbrellas which they might feel are not so protective as they used to be in the past… Without wishing to exaggerate things, there is a perception that the nuclear factor is back on the table and it is growing in its relevance in terms of decision making, in terms of what nations do.”

Rob Young speaks to Rafael Grossi, Director General of the International Atomic Energy Agency.

The IAEA was founded in 1957, and is an autonomous international organisation within the UN system. Its job is to promote the safe, secure and peaceful use of nuclear technology, and to check that nuclear material is not used for military purposes, including nuclear weapons.

Grossi, a former Argentinian diplomat, was appointed in 2019 and has steered the IAEA through multiple challenges. When Russia invaded Ukraine in 2022, concerns were raised about the prospect of nuclear weapons being used, but also about Ukraine’s nuclear power plants coming under attack.

The organisation’s resources were stretched further still when the recent Middle East conflict began. The US, along with Israel, have had concerns over Iran’s nuclear ambitions for many years, and reject the country’s claim that their nuclear program is only for peaceful purposes.

Rafael Grossi is considered a front-runner to become the new Secretary General of the UN which he believes should be accepted more as a keeper of the peace.

“The biggest risk in motion pictures is to not take a risk. You have to be putting it out there and offering people something new, and that's what will get them out of their houses.”

Katie Razzall speaks to Oscar-winning filmmaker Christopher Nolan.

The 55-year-old, whose directing credits include Inception, Interstellar and Oppenheimer, is widely considered one of the 21st century’s most influential filmmakers.

Born in London in 1970, his career began in the mid-1990s, when he would proofread scripts, operate cameras and direct for corporate information films. Barely a decade later, he was chosen to direct Christian Bale as Batman in The Dark Knight trilogy, setting a new standard for how superheroes were portrayed on screen.

A string of blockbusters followed, making him one of the highest-grossing directors of all time, and was later knighted in 2024 for his services to film.

He’s now releasing his latest project, The Odyssey - an ambitious adaptation of Homer’s ancient Greek story, starring a Hollywood A-List cast, including Matt Damon, Anne Hathaway and Zendaya.
