Catherine O'Hara admits she would 'never know' if Seth Rogen was high 'all day'

Catherine O'Hara has confessed that she couldn't tell whether Seth Rogen was high or not while working alongside him on set.

The pair have been joined at the hip throughout the last year while filming the upcoming Apple TV+ series The Studio together - but the actress still struggles to determine if her co-star is stoned or not.

Take a look at what O'Hara and her fellow Canadian told UNILAD about how he slotted his weed smoking in while they were collaborating here:

Rogen has roped in the A Team of A-listers for his latest project with childhood best friend Evan Goldberg, with who he has created cult classics such as Superbad, Pineapple Express and This Is the End.

The comedian, 42, takes the lead as the newly-appointed head of Continental Studios, Matt Remick, who is tasked with stepping into the role of O'Hara's character Patty Leigh after she's unceremoniously sacked.

Stars including Kathryn Hahn, Ike Barinholtz and Chase Sui Wonder make up the extraordinary cast, while there's a host of jaw-dropping celebrity cameos in the ten-part show too.

Rogen and his 'core team of infighting executives' struggle between green lighting films with actual substance or movies with the potential to make big bucks at the box office in The Studio.

The synopsis explains: "They wrangle narcissistic artists and craven corporate overlords in the ever-elusive pursuit of making great films.

"With their power suits masking their never-ending sense of panic, every party, set visit, casting decision, marketing meeting, and award show presents them with an opportunity for glittering success or career-ending catastrophe.

"As someone who eats, sleeps, and breathes movies, it's the job Matt's been pursuing his whole life, and it may very well destroy him."

While taking on the lead role in The Studio, Rogen is also credited as a writer, director and executive producer - and he admitted to UNILAD that spinning all these plates meant it was inherently a 'busier job'.

The Superbad actor is renowned for his love of weed and even co-founded the company Houseplant - a lifestyle brand rooted in cannabis products - with Mikey Mohr and long-time collaborator Goldberg.

He's previously admitted to smoking weed 'all day, every single day' since he was about 20-years-old, so a lot of people will naturally be wondering how he fit this habit in while shooting The Studio.

Speaking to UNILAD ahead of the show's debut on 26 March, O'Hara, 71, revealed that she has no idea whether her co-star was high or not during the filming process.

The Home Alone legend explained: "People ask me, ‘Is he stoned? Is he smoking all day?’ If he is, I would never know it.

"I don’t know if I’ve ever worked with anyone who is more aware of everything going on on the set.

"[Rogen] is director, producer, star in the scene and so aware, so collaborative and so loose and fun, but on the money. It’s crazy. Really, [he is] seriously impressive."

Rogen then chimed in to admit he is a 'little stoned all the time', before emphasising that his liking for weed would never come before his work.

"I would never prioritise weed smoking over actually filming the show," he laughed, before adding: "There’s a lot of downtime on sets as well. I’d say I kept up a pretty good pace."

O'Hara commented that whatever he's doing seems to be 'working' swimmingly, while saying in jest: "I wish it would work for me!"

Cannabis clearly sparks creativity in Rogen, however, he did admit that weed 'doesn't work for most people' the way it does for him, while joking that he 'doesn't offer it to the other cast members'.

He previously suggested that artificial intelligence would 'need a lot of weed' to write a good TV show while discussing the prospect of the software replacing screenwriters in the future.

O'Hara went on to reveal that she's 'tried to smoke some weed' on a handful of occasions in her life, but it causes whatever emotion she is feeling to be 'heightened'.

She told UNILAD: "The few times that I’ve tried to smoke some weed, it heightens whatever I’m feeling before I smoke it. So if I’m with friends and really loose, then that will be heightened.

"If I have the least bit of...I don’t know, self consciousness, then it’s just…'Are you stoned? Are you stoned now? Is everybody okay? Are you feeling what I’m feeling?’

"It’s like no. I don’t do any drugs well. I like alcohol. But drugs, I don’t."

The Studio will premiere globally on Apple TV+ with the first two episodes on Wednesday, March 26, 2025, followed by one episode every Wednesday through May 21, 2025.
