Ewan McGregor, Olivia Wilde& More to Guest on Season 2 of HBO Comedy DOLL & EM

DOLL & EM, the comedy series starring Emily Mortimer (HBO's "The Newsroom") and Dolly Wells ("Bridget Jones's Diary"), will return for its second season SUNDAY, SEPT. 13 (10:30-11:00 p.m. ET/PT) on HBO. Guest stars on the six-episode season include Ewan McGregor, Olivia Wilde, Evan Rachel Wood and Mikhail Baryshnikov.

The new season will again be directed by Azazel Jacobs and produced by Alessandro Nivola with Kevin Comer under Nivola and Mortimer's King Bee label. BAFTA winner Andrew Eaton will executive produce along with Lucy Lumsden, the show's commissioner for Sky. DOLL & EM is an original production from UK broadcaster BSkyB and has just aired on Sky Living in the UK.

Written by and starring real-life best friends Mortimer and Wells, DOLL & EM debuted on HBO in March 2014. The six-episode first season explored what happens when a Hollywood actress hires her childhood friend as a personal assistant while making a film in Los Angeles. A bittersweet, intimate portrait of female friendship, the series followed their relationship through unexpected COMPLICATIONS and surprising twists.

In the second season, the two write an off-Broadway play together in an effort to do something creative on equal footing. They even manage to hoodwink Evan Rachel Wood and Olivia Wilde into appearing in it, with Wood playing Doll and Wilde playing Em.

After packing up her life in London, Doll has moved in to Em's Brooklyn basement, only to find that living in the lap of her friend's family is surprisingly lonely. Meanwhile, their play is jeopardized when Em gets cast in a Hollywood action thriller opposite Ewan McGregor and threatens to abandon their passion project.

Chaos ensues as Doll and Em start rewriting the play to reflect their growing frustration with each other, and Wilde and Wood begin to lose faith in the production.

Will they resolve their differences and restore balance to their friendship by curtain call, or will things finally fall apart forever for the best friends?

Among the critical raves for the first season, the Los Angeles Times observed, "It's as complicated a duet, in its way, as that of 'True Detective,' and as well-played and rewarding, the more so as series about female friendship are in proportionately short supply."
