Amazon will premiere season one of “Catastrophe” — a U.K.-produced comedy featuring Rob Delaney and Sharon Horgan — with all six episodes available for streaming Friday, June 19, exclusively to Prime members in the U.S.

The half-hour comedy, set in London, is about Rob, an American man (Delaney, “Key & Peele”) and Sharon, an Irish woman (Horgan, “Pulling”) who struggle to start a relationship after she unexpectedly becomes pregnant. The series was created and written by Delaney and Horgan.

“Catastrophe” will be available in June exclusively for Prime members in the U.S. and will come to Amazon Prime in the U.K. later in 2015.

Amazon announced the licensing deal for “Catastrophe” with Avalon Television in January. The first season aired on the U.K.’s Channel 4 and the series has been renewed for a second season.

“Catastrophe” guest stars include Carrie Fisher (“Star Wars”) as Rob’s eccentric Bostonian mother and Ashley Jensen (“Ugly Betty”) as Sharon’s unpleasant friend, Fran.

The series is an Avalon Television production with co-producers Birdbath Productions and Merman. “Catastrophe” is produced by Jack Bayles and directed by Ben Taylor. Exec producers are Richard Allen-Turner (“Workaholics”), Kara Baker (“Iliza Shlezinger: Freezing Hot”), Delaney, Horgan and Jon Thoday (HBO’s “Last Week Tonight with John Oliver”).
