In 2002, Ghatak landed a leading role in Andrew Lloyd Webber's production of A. R. Rahman's Bombay Dreams[1] at the Apollo Victoria Theatre, London, directed by Steven Pimlott, where he was cast alongside Raza Jaffrey and Preeya Kalidas.
Ghatak's other notable performances at the Royal Court Theatre include Shades/Unheard Voices, The Spiral, Rough Cuts and the ground-breaking The Low Road by Pulitzer Prize-winning Bruce Norris and multi Olivier Award-winning director Dominic Cooke.
A powerful and tumultuous mix of touching self-awareness and pig-headed selfishness, Amir both warms and chills the heart whilst searching for acceptance and Ghatak's prowess truly shines from the very first moment he steps on stage; a platform he does not leave until the final light goes out, having delivered a performance that can only be described as energy-sapping as it is glorious."
Following on from The Kite Runner, Ghatak joined the original cast in the first stage version of Yann Martell’s novel Life of Pi at the Sheffield Crucible.
