As You Like It is a pastoral comedy by William Shakespeare. With its explorations of sexual ambivalence, As You Like It speaks directly to the twenty-first century. Rosalind's authority in the play grows from new ideas about women and reveals that Shakespeare's heroine reinvents herself for every age. But the play is also deeply rooted in Elizabethan culture, and through it Shakespeare addresses some of the hotly debated issues of the period. The play features one of Shakespeare's most famous and oft-quoted lines, "All the world's a stage", and has been adapted many times for radio, film, and musical theatre.
