Remember that scene in The Princess Bride where Westley, Inigo, and Fezzik break into the castle to save Buttercup?
They’re collectively wounded, and the gate is guarded tightly, but they devise a brilliant plan to prop the giant Fezzik on a wheelbarrow and light him on fire. They make themselves appear extremely intimidating and so terrifying that the opposition has no choice but to surrender.
The power of pure size, apparent fortitude and perceived dominance – even if somewhat feigned – goes a long way. Robert Williams may not be 100 percent, and he may not be his usual spry self, but his mere presence alone plays a role in overpowering the Heat.
