10 Times Movies Got Weapons Wrong

In X-Men 2, a military scientist called William Stryker believes a war between humanity and mutants is brewing. As a result, he orders his soldiers to break into the X-Men's home so he can neutralise and weaponise them for his own agenda.

When one of the men sees a mutant child, he blasts him in the neck with an anaesthetic dart, rendering him unconscious. Moments later, the soldiers try to use the same type of dart against a 6ft 6-tall mutant called Colossus.

Here's the problem with how tranquilliser guns are depicted in film: there is no anaesthetic dosage that works exactly the same on everyone.

The bigger the person, the more anaesthetic they need. If the dart in question was designed to knock a child out, it would have almost no effect on a man of Colossus's size. If it was designed to knock out a fully-grown man, a child could overdose or even die if they received the same dosage.

If Stryker's squad wanted to neutralise the X-Men, he should have used knockout gas.
