Alright, completely realistically?

First off, we have to eliminate everyone who actually can't contribute anything in that type of situation in reality (meaning their real self's, and not character's they played). For example, I'm a bodybuilder and can tell you from experience being muscular isn't goo for much else other than lifting heavy things up, so someone like the Rock is out, because that's his only realistic skill...he's not actually the badass who can fight and shoot things like in the movies...Also seeing a lot of Aubrey Plaza responses, but like...again, what can her real-self do?

So with that rule:

Adam Driver...Why Him? Before he started acting his was an Active Duty Infantry Marine; though some skills like shooting are perishable, he could relearn them quickly, and definitely has the survival skills I'm looking for.

Gal Gadot...Why her? Before she started acting she was an IDF (Isreali Military) hand-to-hand combat intructer. So, military experience, plus specific hand-to-hand experience she could teach others. Plus she's smoking hot.

Harrison Ford...Why him? Pilot and past professional carpenter. Flying is a great skill to have, plus he could explain to people how to build things.

Steve Buscemi...Why him? Former FDNY firefighter; firefighting skills, and I'm assuming some other rescue/paramedic type skills to go along with it.

Ken Jeong...Why him? He's an actual doctor. Really obvious, can save lives in medical situations.

That's all I can think of, but if anyone knows any other celebrities with real skills in real life, I'll add it.
