The Indian actor played game show host Prem Kumar in Danny Boyle's Oscar-winning movie in 2008 and admits he still fields questions about the box office hit two years later.
Now Kapoor, who went on to land a role on hit U.S. drama 24, is urging fans and friends to stop asking him about his Slumdog success.
