Dear Brutus is a 1917 fantasy play by J. M. Barrie, depicting alternative realities for its characters and their eventual return to real life.

The title is a reference to a line from Shakespeare's Julius Caesar: "The fault, dear Brutus, is not in our stars but in ourselves" (which is quoted in full by Mr. Purdie near the end).

[1] The play was revived in 1922 at the same venue for another 257 performance run, with du Maurier again in the cast along with Mabel Terry-Lewis, Alfred Drayton, Ronald Squire and Joyce Carey.

[2] Several reviewers commented that despite the quotation from Julius Caesar in Barrie's title, the Shakespeare play that repeatedly came to mind was A Midsummer Night's Dream.

[2][3][4] The theatrical cartoonist of The Illustrated Sporting and Dramatic News drew the aristocrat and the butler in Act 2 as Titania and Bottom, and the philanderer, his wife and mistress as Lysander, Helena and Hermia.
