Hrithik Roshan-Karisma Kapoor
The film in question is Fiza (2000). When Khalid Mohamed made this not-so-unusual casting, Hrithik was just a film old (Kaho Naa... Pyaar Hai had released earlier in that year) while Karisma had almost a decade-long experience in the profession.
While putting together the cast for his film, the critic-turned-filmmaker took a leaf out of Mansoor Khan's book and ensured that the focus remained on the siblings.
Though the chemistry they shared was good, the box office fate wasn't very encouraging.
And the nomination for the Best Bollywood Sibling goes to...
Emraan Hashmi: For playing brother to Bipasha Basu in Vikram Bhatt's Footpath (2003).
