Both Hugh Grant and Josh Hartnett have worked with filmmaker Guy Ritchie before starring in Operation Fortune: Ruse de guerre. Hartnett previously starred on Guy Ritchie’s Wrath of Man in 2021, while Grant worked with the filmmaker on The Gentleman in 2019. Suffice it to say, the pair had an idea of how Ritchie operates as director, and they discussed this with Collider.

Grant and Hartnett shared what it’s like on the set of Operation Fortune: Ruse de Guerre. Grant said he was initially uncomfortable about the director’s spontaneity since he likes to prepare.

"Well, it's alarming. That is alarming up to a point, and I have had tense moments with him about it because… I don't know why, I like very, very deep, thorough preparation. It makes me marginally less terrified on the day, but actually, there is another way to go about the whole acting business, which is to think, “Well, I have no preparation, let's just wing it. In a way, that takes pressure off because you think, 'If there was no script and I didn't have to learn it, and there's no expectation here…' So it can work in your favor, but it's alarming. It's alarming to act commando the whole time.”

Hartnett also shared his two cents on the director’s filmmaking technique. Like Grant, he had reservations but ultimately trusted the director’s process.

“Acting commando is about exactly the way you have to put it. It's scary at first, but once you rip the Band-Aid off, I think it's comforting knowing that the director is not exactly certain what he wants until he sees it, and then when he sees it it's locked in. That, to me, means that he's really paying attention and that he's sculpting something in the moment.”

Hugh Grant Had Dinner With 10 Different Aubrey Plaza'sAubrey Plaza with a gun in Operation Fortune Ruse de GuerreIn addition to working with Guy Ritchie, the pair also talked about working with Aubrey Plaza. Plaza is the film's only female lead, and the two actors shared what it’s like having her on set. Grant said, “Well, yeah, she's a great comedian. You really, really don't know which way she's going to go at any moment, not only on the set, but off the set. I've had dinner with about 10 different Aubrey’s. They look the same, but…”

Hartnett butted in and said, “Yeah, Hey. I would agree with that. I think Aubrey is multitalented, and we had a lot of fun on set trying to figure out exactly who was going to get the snarky remark. It was always Hugh, I think. He ended up getting the brunt of it. From my perspective, being able to improvise with these guys was really intimidating.”

Operation Fortune: Ruse de Guerre is now in theaters.
