August Rush (2008)

A charismatic Irish rock guitarist (Jonathan Rhys Meyers) and a young classical cellist (Keri Russell) have a chance encounter one glorious night above New York's Washington Square. Torn apart by fate, they leave in their wake a baby boy orphaned by circumstance. Years later, performing on the streets of New York and cared for by the colourful character Wizard (Robin Williams), August Rush (Freddie Highmore), uses his remarkable musical talent to find and reunite the parents from whom he was separated at birth.
