Actor Sean Hagan practiced at the gym with Stunt Coordinator Bill Leaman for several weeks in order to safely recreate Booth's twelve-foot jump from the Presidential state box. However, since the real Booth broke his leg during the jump as a result of catching his boot spur on the Treasury Guard Flag, Costume Designer Martha Timlin built several customized safety features into Hagan's costume. To avoid Booth's fate, Timlin substituted Hagan's boot spurs with shaved-down Japanese Yen, which were guaranteed to look authentic from the camera, but posed no harm to the actor. Specially designed soles were also placed in Hagan's boots to cushion his fall.
