The Character: James Stewart’s rabbit-befriending nice guy is easily the most pleasantly insane person on this list. If your delusion (or is it?) causes you to see a giant rabbit, things aren’t necessarily all that bad.

A heavy drinker, Elwood has had Harvey (the giant titular rabbit) by his side for years, and is largely accepted within his neighbourhood.

Even his sister - who finds her patience tested to its limits by her brother’s six-foot-plus lagomorph - comes to accept that the world’s a better place for this particular eccentricity.

Craziest Moment: Elwood casually puts in an order for two martinis at the bar.
