As his success continued to unfold, Neil made the transition to writing for the Broadway stage in 1956. It wasn't long before he achieved a major triumph with the hit play "Come Blow Your Horn" in 1961, followed by the equally successful "Barefoot in the Park" and "Little Me" the subsequent year.
Neil's remarkable plays were not limited to the stage, as several were adapted into successful films, including the iconic "The Odd Couple", "Barefoot in the Park", and "Sweet Charity".
