 Two versions of the plane recognition scene exist. On the 2001 VCI/Cinema  Club DVD, Patrick Mowers ad lib "No, but I know a Fokker when I see one" is  used. This was removed prior to the films theatrical release in favour of a  different take featuring the scripted response "well, Bristols usually come  in pairs" in order to get to get a lower certificate. The Bristols version is  the one used on BBC TV and the later 2003 Special Edition DVD release  included both versions.
