“Tuesday” offers a Julia Louis-Dreyfus you’ve never seen in “a mother-daughter fairytale” like no other.

The brilliant comedian with the impeccable timing has disappeared in an eye-opening, heartrending performance as Zora, an American single mother in London whose only child, her teenaged daughter Tuesday (Laura Petticrew), is dying.

The film begins with Death – in the form of a size-shifting, talking macaw – visiting the terminally ill to wave a wing and send them into the afterlife.

“I know it’s very ‘out there.’ The script was sent to me — and I was immediately riveted. But,” Louis-Dreyfus, 63, emphasized in a Zoom call, “I needed to meet the writer-director because it’s, as you can imagine, so unusual and so fantastical. And so ‘out there’!

“I needed to make sure that we were on the same page and that I understood her plan for the film, utterly and completely.’

She met with Daina (pronounced Dinah) O. Pusić, “for a very long time actually, over a Zoom. And decided to sign on for this “extraordinary adventure” of ‘Tuesday.’ ”

As to tackling an unrelentingly intense dramatic role, “Yes, it is a departure. It was a great opportunity for me to really sink my teeth into a very dramatic arc. And I was happy to do so.”

Zora, she decided, “is in enormous denial. She has isolated herself from her entire world, including her own daughter who is so profoundly ill. She is operating at a subconscious level.

“This was something that I could imagine. I did not, of course, judge it. Even though you can see how some people might at first glance call stupid certain decisions she makes. But I’m hopeful that people understand how these decisions come to pass.”

What audiences see in “Tuesday” – the bird that is Death – is miraculously realistic but filming was quite different.

“There was no bird but there was an actor named Arinzé Kene who played the bird. He was on set with us every single day. And it was his humanity and his extraordinary performance that gave life to this character of the bird. We played off of him.

“The animators essentially drew over him and used his physicality and his facial expressions and his emotional life to inform the animation. Without him, this movie could never have happened. Because it made all the difference.”

What might audiences take from “Tuesday”?

“That people are entertained and moved by the film of course — and then I am hopeful that it engenders conversations around the subjects of grief and loss, death and dying.

“That it maybe can open up hearts in a way that might not have been otherwise.”
