8. Alan Rickman & His Gun Issues
Bad guys in cinema are supposed to be fearless, steadfast in their deluded beliefs that their actions are right and "for the greater good". Shooting someone shouldn't be a problem for such a villainous character as Hans Gruber then, right? Wrong. Alan Rickman, who portrayed Gruber, had an uncontrollable habit of flinching and wincing whenever he fired a gun in Die Hard, to the point that Director John McTiernan had to "smash cut" away from his face whenever he fired a gun. If you look at Rickman's face after he has just shot Takagi, you can see him wincing.
