Pete Davidson and Ella Purnell cast in That Time We Met

Pete Davidson and Ella Purnell are to star in the rom-com That Time We Met.

The pair have signed up to feature in the "cosmic" flick that is being directed by Nick Lieberman from a script penned by Mitchell Winkie.

Sales on the picture will be launched by WME Independent at the upcoming American Film Market.

That Time We Met tells the story of a new couple who discover their unborn child is destined to save humanity. The problem is that they've just had their first date and now hate each other.

Davidson is a stand-up comedian who featured on Saturday Night Live from 2014 to 2022 and has also appeared in movies including The King of Staten Island, Bodies Bodies Bodies and The Pickup.

He is also slated to star in the David Leitch heist flick How to Rob a Bank, which is scheduled for release in September 2026.

Meanwhile, British actress Purnell, 29, has featured in TV shows including Yellowjackets, Fallout and Sweetpea.

Away from his acting and comedy career, Davidson has dated a string of famous women - including Kim Kardashian, Ariana Grande and Margaret Qualley - but admits that he was frustrated to be known for his romances instead of his comedic prowess.

The 31-year-old star said on The Breakfast Club: "It just got to a point where I was... I got really tired of my whole career just being like my personal life. And living through that is it's sort of traumatic. Like not to be like lame, but like it's traumatic to live in your own c*** all the time."

Pete also hated the experience of being sexualised by the public.

The comedy star explained: "I don’t want to victimise myself in any way because I’m cool, but the sexualisation of me — if that was a girl, people would be like, there would be a march for it... Seriously. You're just talking about my d*** all day."

Pete is expecting his first child with girlfriend Elsie Hewitt and explained that his impending fatherhood has given him a different outlook on life.

He told People magazine: "I'm just excited to take care of the little one. The second I found out the news, I was like, 'Oh wow, what I do is just a job.'

"I realised I was kind of basing my happiness on work, which is ridiculously unhealthy. So it gave me this weird sense of calmness, where this is just a job and now I have someone to do it for."
