Bombai Ka Baboo (English: Sir from Bombay) is a 1960 Hindi film directed by Raj Khosla and written by Rajinder Singh Bedi. The film stars Dev Anand and Suchitra Sen in her rare appearance in Hindi cinema.
Though the film was a thriller, it treads into rare Hindi film territory by hinting at incest between the lead pair.
Except for the "Brother-Sister" angle, the plot of Bombai Ka Babu is inspired by O'Henry's short story, A Double-Dyed Deceiver. The story of the movie Zameer starring Amitabh Bachchan is very similar to this movie.
With classic songs like 'Chal ri sajni, ab kya soche', by Mukesh, and 'Deewana mastana hua Dil' by Mohd. Rafi and Asha Bhosle, the film was a musical masterpiece, and is considered one of finest films music by S. D. Burman and lyrics by Majrooh Sultanpuri. The film director Raj Khosla was also the film maker behind Dev Anand's suspenses like CID (1956) and Kaala Paani (1958).
