Derren Brown meets Sherlock stars Martin Freeman and Amanda Abbington in a new clip from Stand Up To Cancer 2014 and treats the stunned pair to his very special brand of illusion.

A raucous night of fundraising hosted by Davina McCall, Alan Carr and Dr Christian Jessen, Stand Up To Cancer 2014 airs at 7pm on Friday 17 October on Channel 4.
