The UN's recent decision to observe October 2 as the International Day of Non-Violence was another cause for the celebrations.
Besides "Lage Raho", the second film in the Munnabhai series, Richard Attenborough's "Gandhi" and Shyam Benegal's docu-drama "The Making of Mahatma" were also screened as part of the Mahatma Film Festival.
Sectarian riots in Nepal last month killed at least 33 people and left thousands homeless. Hope Munnabhai brings peace amongst the clashing groups and teaches them the ways of the Mahatma.
