See Naomi Watts in trailer for Princess Diana biopic
"There's a huge amount of pressure and I tried to say no a few times since this movie is going to be so open to public opinion and that's a scary thing for an actor to subject herself to," Watts told The Daily Beast.
"Diana" will emotionally pull the viewer back to what so many remember the late royal as; a humanitarian, a people person, a mother and someone who was continuously in the public eye.
"It was a story that was going to be told, and I just felt like she was a fascinating woman," Watts told ABC.
The film will release in theaters Oct. 10.
