Pressure is a play written by David Haig. It made its world premiere at the Royal Lyceum Theatre, Edinburgh in May 2014, a year later than originally planned, before transferring to the Chichester Festival at the end of the same month. The play centres on the true story of James Stagg and Operation Overlord, in particular the weather-forecasting for the D-Day landings and the resultant tensions between Dwight D. Eisenhower, James Stagg and Irving P. Krick.
