Lake Bell

... and then after, I directed this short (El Tonto) for The Director’s Bureau, this thing that Roman Coppola was curating.

In February 2014 she said her next project would be What's the Point? (And Other Fair Questions About Marriage), a film she would write and direct, which was eventually renamed I Do... Until I Don't.

Bell made her writing and directing feature film debut at the 2013 Sundance Film Festival with In a World.... which she wrote and directed and in which she starred She describes the film as "a comedy about a female voice-over artist and family dysfunction and relationships. I’m obsessed with the voice-over world, so it makes sense for me." The film was picked up by Roadside Attractions and Sony.

In 2011, Bell began dating Scott Campbell, an artist and tattoo artist. The two met when he played himself in an episode of the second season of How to Make It in America. The couple became engaged on Bell's birthday in March 2012 and were married on June 1, 2013, at the Marigny Opera House in New Orleans, Louisiana.

Bell had a lead role alongside Kate Bosworth in the 2012 thriller Black Rock.

“The film is about a milk-drinking, lactose-intolerant misanthrope on a quest for real human connection. Being an ordinary, unoriginal and unloved woman, she instead becomes so wrapped up in her own quiet neurosis that she finds herself physically stuck in a full body girdle. I wrote and directed Worst Enemy in 2010 as an experiment to see if I could take on being a filmmaker.”
