Dev Anand was originally signed for the lead role and the title song, penned by Sahir Ludhiyanvi, was also picturised on him. Dev Anand wanted the heroine Ameeta to be replaced for which director Nasir Hussain didn't agree. So Dev Anand walked out and so did Sahir. Shammi Kapoor was then given a chance for the lead role, inspite of him being unsuccessful till then. Majrooh Sultanpuri was roped in as replacement for Sahir, who wrote the remaining songs for the film.
