Britney Spears' song Toxic sampled a part of the song Tere Mere Beech Mein.
K. Balachander had shown a preview of the film to legendary filmmaker Raj Kapoor before it's release. Kapoor liked the film but not the ending, which he found to be overly sad. He suggested to Balachander to change it to a happy ending, but the latter refused and stuck with the sad ending.
In the scene in which Rati Agnihotri mixes the burnt remains of a photograph into her tea and drinks it, she really did do that. She did not realize at that time that the photos back then had toxic chemicals like silver in them. Fortunately she did not suffer any ill effects.
