Indian Prime Minister Manmohan Singh Monday congratulated on the winning of eight Oscar prizes by the "Slumdog Millionaire," a movie based on the slum life of Mumbai.

With heavy participation by Indian artists and children, the Mumbai-based film swept the 81st Academy awards winning eight Oscars.

Directed by Briton Danny Boyle and based on Indian author and diplomat Vikas Swarup's novel "Q and A", the film had received 10 Oscar nominations, including three for Indian music maestro A.R. Rahman and one for Resul Pookutty for sound mixing.
