However, there was one legend who was actually scared of working with the director before things kicked off – Meryl Streep.
In fact, the Devil Wears Prada star admitted she was ‘terrified’, because of his previous work on spooky American Horror Story – and ended up ‘unprepared’ for the joy he brings to set.
Speaking to Metro.co.uk and other press ahead of the release, the 71-year-old told us: ‘I was a Ryan Murphy fan, but I was also terrified of Ryan Murphy because of American Horror Story.
‘I was pulled to it in its scariness and it was beautiful, horrible, grotesque and something very, very true. So I knew he had a sharp eye for what’s really scary in life.’
Thankfully, Meryl’s fear turned to love very, very quickly – and we’re absolutely not surprised.
‘I have to say I was unprepared for the joy he brings to the work and the love and the size of that. I loved this experience making this film,’ she continued.
‘I was unprepared for his big-hearted gesture of this piece. It’s how attached he is to try and get the truth of something, but he’s unafraid of the great big gesture and that’s what this is.
‘It’s just a big embrace and, boy, do we need it right at this time of the world.’
Well, she’s not wrong.
The Prom follows former Broadway stars Dee Dee Allen (Meryl) and Barry Glickman (James), who jump at the chance to resurrect their battered public image after learning about Emma Nolan (Jo Ellen Pellman), a student who is banned from her high school prom with her girlfriend.
The pair enlist Angie Dickinson (Nicole) and Trent Oliver (Andrew) and get on the first tour bus to lend a helping hand – but things don’t go quite to plan as Mrs Greene (Kerry Washington) gets in their way.
Will they be able to pull their star power together and give Emma a night she definitely deserves?
Lifting the lid on playing a fading star, Meryl explained why divas like Dee Dee are her favourite.
‘It was such a stretch playing someone so vain and so overreactive, a big fat narcissist. I don’t know where I pulled it from,’ the Hollywood legend said.
‘I love playing that character. I am all of those things probably but I am not a diva and those are big shoes for me.’
‘I loved playing someone who walks in and thinks she owns the room,’ she added. ‘Of course, she doesn’t, but I loved that kind of fun. Everybody takes the p**s out of her all through and that was fun too.’
We can’t wait to see what Meryl does next.
The Prom is in select cinemas now, and will launch on Netflix on December 11.
