Leslie: (On fame) It really hasn't affected my life that much. On the ladder of celebrity, I'm on the lowest rung. I get approached. People definitely speak to me. It's always nice. No one has ever been rude, although people do think it's appropriate to say things like, "You look so much fatter on TV."
Leslie: (On ambition) Many actors and actresses think, 'Oh, I've got to be the biggest movie star or the biggest television star and I'm going to scratch and claw and do whatever I can to get to the top,' – that's not me at all. I can't even imagine being in that mindset.
Leslie: (On auditioning) There are many times at an audition where I'll be waiting to go in and I can't believe the behavior of the other actresses in that room. They'll do anything to freak-out the other actresses - intimidate, make rude comments - and you just have to know that they're coming from such a sad place that you can't pay any attention to it.
Leslie: (On acting) This is something that has truly fallen into my lap. I can't put restrictions on it and say, 'I have to keep acting for the next fifty years,' as acting doesn't work like that. It could all go away and you could not work for years and years.
Leslie: (on Popular) I was lucky to be involved in that. I mean, I wish I could take you with me through pilot season and see just how hard it is to get a show on the air. It's crazy. There's so much stuff that's really good that will never make it - and we'll never know about it. So the fact that that freaky show with my character was on American television for two years - that's pretty cool.
