Back in 2013, Lake Bell, an actress known for TV and film roles including Boston Legal, It's Complicated and No Strings Attached, wrote and directed In A World..., a smart comedy about a female voiceover artist trying to land a job narrating a blockbuster movie trailer. (We did a segment about the film, and about voiceovers, as a matter of fact.)

She's back as the writer, director and star of the new film I Do...Until I Don't, which follows three couples who become entangled with a documentarian who wants to make a film arguing that marriage should not be a lifelong commitment, but a seven-year deal with an option to renew. The couples are played by Bell and Ed Helms; Amber Heard and Wyatt Cenac; and Paul Reiser and Mary Steenburgen. It's an engaging movie with a view of marriage that surprised me a little, and it was fun to chat with Bell about it.

We also talk about the world of voices, with which she's sort of obsessed, and about why she and I both change the sounds of our voices depending on our circumstances. She puzzles over how Brits say goodbye on the phone, and I consider the calming power of Minnesota.
