Aaron Taylor-Johnson has seen 'Fifty Shades of Grey' "a thousand times".
Sam and Aaron Taylor-Johnson
The 'Kick Ass' star - who is married to the film's director Sam Taylor-Johnson - was treated to regular screenings of the movie, despite there being a ban on any clips of it being revealed before it's official premiere earlier this month.
She shared: "I haven't been able to show it to anyone. It's the most frustrating thing ever to not be able to get feedback.
"Aaron has seen it a thousand times. He worked on it from the script right through. I needed someone that I could trust to bounce ideas off."
Meanwhile, the 47-year-old director also opened up about the film's sexual nature and insisted that not all of the scenes could become a part of the final movie.
She shared: "Those scenes had to be about sexuality and sensuality, but you can't film it exactly the way it is on the page."
Sam also admitted she was "very sad" when Charlie Hunnam chose to pass on the film.
She told Ireland's The Herald newspaper: "Charlie and I were working really well together. But signing up for one film is very different from signing up for a trilogy. As the process got bigger, I started to sense his fear.
"On the day he called me to say that he just couldn't do it, I knew it was coming, but it was very sad. But then, I truly believe Jamie [Dornan] was meant to be Christian Grey - so, things work out for a reason."
