Produced by Homi Wadia, and written by JBH Wadia, this film surprised me. It lacks their usual emphasis on stunts and crazy special effects, which I always enjoy; but is a solidly entertaining filmi noir more along the lines of Howrah Bridge and C.I.D. (although not nearly as competently done) than of Aladdin. Dwarka Khosla (any relation to Raj?) directed, and the plot is interesting (in spite of the many holes), with good performances and—best of all—spectacular music.
Feroz Khan stars in one of his first roles; as Todd pointed out in a comment elsewhere, he seems to have started off his film career as a poor man’s Shammi Kapoor. If that was his brief from the filmmakers, he certainly lived up to it during the songs at least. I will say that if Shammi and, say, Madhubala or Asha P. had starred, it would have probably taken the film to a whole other level; but as it is Feroz and Chitra deliver consistently if not spectactularly.
