James McAvoy
Scottish Actor
I don't really... go to 'the opening of an envelope.' I don't really turn up to all the events, you know what I mean? If I'm involved, I'll go, and if there's a good friend who needs support, I'll go, but otherwise... I don't go. I'm probably just a bit like my grandparents; I like staying in.
Quote examples
Mekhi Phifer
American Actor
I love anything that really pushes the envelope as far as where it takes your mind. When it's well written and brings you into a world that possibly could be, I think that's the most entertaining for me - to see something that could actually take place and causes you to think.
Quote examples
Gina Torres
American Actress
I have been very, very fortunate on this show, on 'Suits,' where the writers do come to me, and they ask my comfort level and, if they want to push an envelope in a certain direction, if I'm okay with that. And, by and large, I am. I think it's important.
Quote examples
Javed Akhtar
Indian Activist
Very rarely does a mainstream film push the envelope. A film that's so-called mainstream and questions certain norms, certain notions of morality, and gets away with it opens doors. It means the common man, the majority of the people, have accepted it.
