Blethyn another BAFTA Award nomination for Best Actress in a Supporting Role. In 2007, she appeared in the independent Australian coming-of-age comedy Clubland. Playing a character that was created specifically with her in mind, Blethyn portrayed a bawdy comedian with a sinking career faced with the romantic life of her young son, played by Khan Chittenden. The film was released in Australia in June 2007, and selected for screening at the prestigious Sundance Film Festival where it was picked up by Warner Independent Pictures for a $4 million deal and gained glowing reviews. Los Angeles Times film critic Carina Chocano wrote, "the movie belongs to Blethyn, who takes a difficult, easily misunderstood role and gracefully cracks it open to reveal what's inside." The following year, she was nominated for an Australian Film Institute Award and an Inside Film Award for her performance. Also in 2007, Blethyn reunited with Joe Wright on Atonement, an adaptation from Ian McEwan's critically acclaimed novel of the same name. On her role of a housekeeper in a cast that also features Keira Knightley, Saoirse Ronan and James McAvoy, Blethyn commented: "It's a tiny, tiny part. If you blink you'll miss me." The film garnered generally positive reviews from film critics and received a Best Picture nomination at the 2008 Academy Awards. A box office success around the globe, it went on to gross a total of $129 million worldwide. Blethyn also appeared as Márja Dmitrijewna Achrosímowa in a supporting role in the internationally produced 2007 miniseries War and Peace by RAI, filmed in Russia and Lithuania. 2008–2010 In 2008, Blethyn made her American small screen debut with a guest role on CBS sitcom The New Adventures of Old Christine, playing the neurotic mother to Julia Louis-Dreyfus' character in the fourth season episode "Guess Who's Not Coming to Dinner."

Her performance of a sympathetic fugitive of domestic violence and rape that killed her first husband in self-defense earned Blethyn another Primetime Emmy Award for Outstanding Guest Actress – Drama Series nomination.
