Tina Fey and the writer of her new movie Sisters, Paula Pell, have said that comedy is more open now for female comics with the pair describing their time in the writing room of Saturday Night Live as an even playing field.

Fey became the first female head writer of Saturday Night Live in 1999 and while comedy may seem like a boy's club, she said that jokes made it onto the show if they were funny enough, regardless of who wrote them.

Speaking to RTÉ TEN, Fey said: "The great thing about that job was that there was always a kind of even playing field, you had the table read where everyone wrote and they would read them out loud, and everyone laughed or they didn't laugh.

"I think where you get in trouble is when people are theorising something in a boardroom saying 'what I think people want to see is blah blah blah' but when you put it in front of an audience, an audience will laugh at whatever's funny."

Pell, who has also worked on SNL since the 1990s, added, "If you have a crowd laughing at something then you can deny that, and it has momentum to move forward and be made, but if people have already decided in their theories that something gets blocked, then it doesn't get through.

"I think now, all of those floodgates have opened and there have been enough examples of varying gender originated comedies that make the same money, so it's all about money ultimately with some of that stuff."

On their new comedy Sisters, which co-stars Amy Poehler, Fey said: "We did have a lot of fun making the movie, which I keep saying doesn't really matter unless the movie is fun to watch, but I do think the movie is fun to watch also."
