Who should win? Who’s been snubbed? Guardian film editor Catherine Shoard answers your Oscars questions

Guardian writers have been making their pitches for best picture winner at the 98th Academy Awards in our Oscars hustings series.

Has Chase Infiniti been snubbed? Should Train Dreams win for best cinematography? Who’s the bigger monster, Frankenstein’s or Marty Mauser? Guardian film editor Catherine Shoard answers your 2026 Oscars questions.

Thanks very much for all these really well-informed and thoughtful questions! I’ll try to get through as many as possible

1. Vicious circle of looming industry collapse fueling industry timidity.

2. Talent exodus to TV and streaming.

Parasite (2020) and Moonlight (2016) were good – but not the year’s best films. So perhaps 12 Years a Slave (2014).

The Oscar campaign trail is today a very precise, well-monitored and potentially lucrative business – which is why slip-ups such as the failure to police the social media of Emilia Pérez star Karla Sofía Gascón are so surprising/glaring/dramatic.

Red carpet is important for this, but not the most critical part of the campaign by any means, unless something really unusual happens on the carpet. Interviews are far more important – note the Chalamet ballet slip, which occurred in the softest of spaces – as well as general glad-handing.

Reaching up to 100ft, these massive piles contain tonnes of salt that keep roads clear – but pose environmental risks

Most mountains take tens of millions of years to form. Toronto’s newest mountain took just days.

Towering atop the crowns of evergreens, it has no skeleton of limestone or granite. There are no spires, cornices or headwalls. It is simply piles upon piles of snow, mixed with a toxic cocktail of road salt, antifreeze, oil, coffee cups and lost keys. It is the final resting place for the forces of nature that have battered the city in recent weeks – and a daunting environmental hazard.

Experts share tips on dressing as the most authentic version of yourself and avoiding the draw of the latest microtrends

How would you define your personal style? Is it cottagecore? Tomato girl? Whimsigoth? Quiet luxury? Maybe you don’t know what these terms mean (congratulations) and maybe you do (my condolences).

Like unwelcome nose hairs, new microtrends seem to sprout from the depths of social media every other week. In some ways, their pervasiveness has made style seem more accessible than ever. They reduce aesthetics to mathematical equations that you can solve by buying up a bunch of fast fashion. By the time these cheap, mass-produced items dissolve into microplastics – which they will, quickly – other aesthetic trends will have replaced them.

Content creators claim they’ve escaped the 9 to 5, yet as Louis Theroux’s new show reveals, they are mere serfs to algorithms and audiences

Who wouldn’t want to be an influencer? You’re famous and maybe even rich, just for doing what you’d be doing anyway: working out at the gym, hanging out with your mates and mucking about on the internet. You get paid to say what you think (or are at least sent free stuff), and no one’s telling you what to do. Surely only a sucker would do anything else.

At least that is the influencing dream, and many young men are buying into it. “Content creator” has for years been cited as the most desirable career by generation Z and now gen Alpha. The preferred platforms might have changed over time, with streaming on Twitch and Kick now supplanting posting on Instagram and YouTube, but the aspiration remains the same: to escape the drudgery of a desk job.

Tens of thousands of residents and tourists have left UAE since the US and Israel started bombing Iran two weeks ago, leaving beach bars, malls and hotels eerily empty

In the playground of the rich, nobody wanted this war. For decades, Dubai built itself up as a sanctuary of unadulterated consumerism visited by tourists the world over.

But now, the city in the United Arab Emirates faces an existential threat, as the war between the US and Israel and Iran has shaken the foundations of the “Dubai dream” that so many foreigners had bought into.

Thai navy responds to attack on bulk carrier; sources say Iran has deployed a dozen mines in the strait

• How have you been affected by the latest Middle East events?

Over in Senate question time, the foreign affairs minister, Penny Wong, has confirmed embassies in Abu Dhabi and Tel Aviv and the consulate in Dubai all physically closed in the last week.

Wong said the government’s number one priority is to “keep Australians safe at home and abroad”.

She continued:

“The dangerous and destabilising attacks by Iran put civilian lives at risk, including Australian lives.”

More than 3,200 Australians over 23 commercial flights have returned to Australia since the US and Israel attacked Iran, setting off a regional conflict and grounding thousands of international flights.

Wong criticised Nationals senators for “winding up people and stoking fear” to panic buy fuel.

The senator said:

“Petrol companies are telling us that fuel stock continues to arrive as expected and on time but there has been a large change in the pattern of demand and that is having an effect on the supply, particularly in regional communities. We have seen jerry cans coming off the shelves at Bunnings and lines at the pump.”

One of the two members of the Iranian women’s football teams provided with a humanitarian visa to stay in Australia has changed her mind and contacted the Iranian embassy, according to the country’s home affairs minister.

In Australia, people are able to change their mind, people are able to travel. So, we respect the context in which she has made that decision.

Unfortunately, in making that decision, she had been advised by her teammates and coach to contact the Iranian embassy and get collected … As a result of that, it meant that the Iranian embassy now knew the location of where everybody was.

When the global economy was still in the grip of the devastating 1970s oil crises, exposing the chokehold exerted by a few important oil states, the International Energy Agency (IEA) was created, in the hope of limiting future shocks.

Almost half a century on, the IEA’s 32 members have drawn up plans to hit the emergency button, for only the fifth time in its history.
