Hollywood actress Meg Ryan is heading back to the small screen after signing on to produce and star in a new comedy series.

The When Harry Met Sally star will portray a former hotshot editor and single mum in New York in the as-yet-untitled show for America's NBC network.

The programme is being written by former Family Ties scribe Marc Lawrence, according to The Hollywood Reporter.

Ryan is no stranger to Tv - she previously starred in 1982 comedy One of the Boys with Mickey Rooney and Dana Carvey, while she also recently appeared in Lisa Kudrow's Web Therapy.
