Ace Bollywood actor-filmmaker Aamir Khan must make a film on first US president George Washington and win an Oscar for it, says veteran Indian singer Asha Bhosle.

"Since Englishmen can make Oscar (winning) films like 'Gandhi' and 'Slumdog (Millionaire)', Aamir Khan should make a film on George Washington and win the Oscar finally, " said Bhosle.

Earlier, Aamir attended the Oscar ceremony along with filmmaker Ashutosh Gowariker in 2002 when their film "Lagaan" was nominated for the best foreign language film. However, it lost to "No Man's Land" from Bosnia and Herzegovina.
