USA's 'Complications': Jason O'Mara, Jessica Szohr Cast Christine Horn As SPOILERS in Premiere!

USA Network has released all-new casting announcement for their upcoming medical/crime drama, Complications. Ahead of the show's June premiere, actress Christine Horn (Selma) joins the exciting new series from Burn Notice creator Matt Nix, starring Jason O'Mara (Life After Mars) and Jessica Szohr (Gossip Girl).

As previously mentioned, Dr. John Ellison (Mara) is a suburban doctor who used to be at the top of his game in the emergency room. Outside of work, Ellison is dealing with the emotional effects of his daughter's death. With the loss of his daughter, Ellison suddenly finds redemption after he saves a young boy's life from a drive-by shooting. Gretchen (Szohr), a street-smart ER nurse, is caught in the middle when Ellison becomes involved in a gang war.

The concept for the show came about after the Burn Notice creator volunteered at a hospital and witnessed a gang member break into his Echo Park home.

We reported before, in a behind-the-scenes featurette, Nix revealed how his program is intense and exciting for viewers, "The show is about all of the things that come out of this one decision that this doctor makes. The idea in this show is that nothing that anybody does comes without complications."

According to Broadway World, the former cast member of Disney's The Lion King has landed a recurring role on the USA drama. Horn will play Sherry Perkins, the ER charge nurse. Perkins is described as a likeable person with a great sense of humor. But she also runs the hospital like clockwork.

Complications premieres on USA Network on June 18.
