Anne Hathaway is so committed to her acting process that she spends pre-production obsessively researching and studying the script, and her constant questions can be off-putting for filmmakers.

'One of the things that I try to explain to directors who don't know me is that I interrogate everything in prep,' the 43-year-old Oscar winner told her Mother Mary director David Lowery on The A24 Podcast on Tuesday.

'Like everything, even lines that I absolutely love, I just ask every single question. I hold everything up to the light. I poke holes in everything. And I think it I know for a fact it's freaked some of them out.'

Hathaway makes sure to explain to the cinematic maestros that she does this 'because I'm not going to ask a single question when we're on set.'

'When we're on set, I want to be your first lieutenant,' the Somewhere Pictures owner said.

'I want to execute your vision. I just want to hit the ground running and know exactly what we're doing and why. We don't have time for my questions then.'

The 45-year-old filmmaker replied: 'I remember that as well. Even though we knew we weren't changing anything, we went through and talked about every single line.'

Hathaway interjected: 'Some lines more than once [laughing]!'

Lowery and the Dark Cradle singer reunited to promote the fact that their ghostly psychological thriller is now streaming VOD to rent ($19.99) or purchase ($24.99) via A24.

Hathaway played the titular troubled pop star in Mother Mary - featuring original songs by Jack Antonoff, Charli xcx and FKA Twigs - which flopped, only earning $3 million back from its $20 million budget.

Michaela Coel, Hunter Schafer, Kaia Gerber, Jessica Brown Findlay and Chris Evans' wife Alba Baptista also star in the epic melodrama which received a 70% critic approval rating (out of 179 reviews) on Rotten Tomatoes.

By contrast, The Devil Wears Prada 2 is a bona fide blockbuster, amassing $548 million off a $100 million budget, since opening worldwide on May 1.

The native New Yorker has also worked with prominent directors like Garry Marshall, Ang Lee, Jonathan Demme, Barry Levinson, Tim Burton, Christopher Nolan, Nancy Meyers, Todd Haynes and Robert Zemeckis.

Audiences can next catch Hathaway as Odysseus' (Matt Damon) wife Queen of Ithica Penelope in Christopher Nolan's $250M-budget big-screen adaptation of Homer's The Odyssey, which hits IMAX theaters on July 17.

Zendaya, Charlize Theron, Tom Holland, Robert Pattinson and Lupita Nyong'o are also slated to star in the Universal Pictures epic.

The Idea of You producer-star will then portray Ewan McGregor's onscreen wife Denise Platt in David Robert Mitchell's sci-fi dino flick The End of Oak Street, which hits US/UK theaters August 14.

Hathaway produces and stars as author Verity Crawford in Michael Showalter's big-screen adaptation of Colleen Hoover's 2018 thriller Verity, which Amazon Studios will release in theaters on October 2.

The Emmy winner has no less than 10 upcoming projects including Paramount+ limited series Fear Not, Disney+ series Ella Enchanted, Adele Lim's The Princess Diaries threequel, Jonathan Tropper's untitled FBI wedding sting comedy and Ron Howard's war drama Alone at Dawn.

Hathaway originally kicked off her career, at age 18, starring in Garry Marshall's 2001 hit comedy The Princess Diaries after Juliette Lewis turned the plum part down. 

On the personal front, the Bulgari brand ambassador welcomed two sons - Jonathan, 10; and Jack, six - from her 13-year marriage to producer-jewelry designer Adam Shulman.
