Writer and director Krishnan drew on her own experiences as a hospital doctor to produce a confused, sleep deprived and amphetamine fuelled version of late night emergency wards. Raw, concise and perfectly styled, Shadowscan won a host of awards including a BAFTA after its release in 2000.

Since then, Krishnan and her film company, Disruptive Element Films, have created several short films and documentaries and been commissioned to write films for Film Four and The Film Council.
