"I Want You Back" is such a fun rom-com, but also a serious romance in a lot of ways. What drew you to the movie?

I think [it's what you just said]. I like the more serious aspects of the storytelling. I think I was excited for that acting opportunity and challenge, but also found it genuinely funny. And lastly, I always wanted to be in a rom-com, so I was happy that ... I was worrying I was starting to run out of time.

Why haven't they picked you to be a rom-com lead before?

I wasn't ready. I was ready now. I'm glad it happened now.

It was great to see you work so closely with Jenny Slate. What was it working with her on this movie?

Oh, she is a dream. I've been a fan of hers since the first time I started seeing her on "SNL" and all of her work and her amazing performance in "Obvious Child." And then I read her book, "Little Weirds," and I just said, "Oh, here's, this is a really special and interesting person. I hope that she likes me," and we really hit it off. I could not enjoy her company more. I honestly hope that I get to do the Tom Hanks, Meg Ryan thing with her and get to do a handful of these movies. It would be great.

In this film, your character has to juggle two very different romances. What was that like?

It wasn't hard because both Gina and Jenny are excellent. Gina Rodriguez and Jenny Slate, they're both so good at what they do that I [only] had to be present and available for them, and to get to do emotional scenes with them both was an embarrassment of riches.
