Tchin-Tchin, also known as Chin-Chin, is a 1959 play written by Francois Billetdoux. It premiered at the Theatre de Poche in Montparnasse Paris in 1959. The author himself played the role of Cesareo Grimaldi and Katharina Renn played Pamela Pusey-Picq. The playwright Sidney Michaels translated it into English and it opened in London's West End as Chin-Chin in 1960 starring Celia Johnson and Anthony Quayle in the leads. It opened on Broadway at the Plymouth Theatre, (later transferring to the Ethel Barrymore Theatre) on October 25, 1962 and closed on May 18, 1963 after 222 performances and 3 previews. Directed by Peter Glenville, the play starred Margaret Leighton and Anthony Quinn, and featured Charles Grodin. Arlene Francis and Jack Klugman took over the star roles for the last month of the run.
Tchin-Tchin received Tony Award nominations for Best Play, Best Actress in a Play (Leighton), Best Scenic Design, and Best Direction of a Play.
Time Magazine wrote: "Tchin-Tchin is magical. It is also fragile, but it is saved from wispiness by Leighton and Quinn. Excellence is an acting habit with Margaret Leighton, and her Pamela is expectably perfect. Anthony Quinn brings his subtlest gifts to Caesario, a character in whom anguish and sentiment sprout like city flowers between slabs of concrete."
In 2013 Chin-Chin was revived with Felicity Kendal and Simon Callow starring. The first night was at the Theatre Royal Windsor, Berkshire on 16th October prior to a tour of the UK and possibly a West End run.
