Up in Mabel's Room (play)

Up in Mabel's Room is a farcical comedy play written by Wilson Collison and Otto Harbach. It premiered on Broadway in 1919 and became a popular production, known for its suggestive humor and situations deemed risqué for the era.

The play revolves around Mabel, a young woman whose reputation is endangered by a series of misunderstandings and compromising situations. Much of the comedy derives from mistaken identities, eavesdropping, and the frantic efforts of various characters to conceal their actions and motives. Common themes include marital infidelity (or the appearance thereof), societal hypocrisy, and the pursuit of pleasure.

Up in Mabel's Room is considered a classic example of early 20th-century American farce. While its humor may seem dated to modern audiences, it offers insight into the social mores and comedic sensibilities of the time. The play enjoyed numerous revivals and adaptations, including film versions. Its success demonstrated the public appetite for lighthearted entertainment that gently poked fun at social conventions.
