Blithe Spirit is a comic play by Noël Coward, described by the author as "an improbable farce in three acts". The play concerns the socialite and novelist Charles Condomine, who invites the eccentric medium and clairvoyant Madame Arcati to his house to conduct a séance, hoping to gather material for his next book. The scheme backfires when he is haunted by the ghost of his wilful and temperamental first wife, Elvira, after the séance. Elvira makes continual attempts to disrupt Charles's marriage to his second wife, Ruth, who cannot see or hear the ghost.

Present Laughter is a comic play written by Noël Coward in 1939 but not produced until 1942 because the Second World War began while it was in rehearsal, and the British theatres closed. The title is drawn from a song in Shakespeare's Twelfth Night that urges carpe diem. The play has been frequently revived in Britain, the US and beyond.
