When someone in a movie needs saving, most of us are too busy cheering on the search party to take the time to consider just how much rescuing that character would actually cost.

But when a member of the Quora community recently posed that question about Matt Damon, an actor who often plays characters in need of aid, user Kynan Eng decided to figure it out. Based on estimated fictional costs, Eng calculated that over $900 billion has been spent “attempting to bring Matt Damon back from distant places.”

Here’s how he broke it down among Damon’s films:

“Courage Under Fire (Gulf War 1 helicopter rescue): $300k

Saving Private Ryan (WW2 Europe search party): $100k

Titan A.E. (Earth evacuation spaceship): $200B

Syriana (Middle East private security return flight): $50k

Green Zone (US Army transport from Middle East): $50k

Elysium (Space station security deployment and damages): $100m

Interstellar (Interstellar spaceship): $500B

The Martian (Mars mission): $200B

TOTAL: $900B plus change”

That’s nearly a trillion dollars spent on saving one person. Although he did give us Good Will Hunting, so we suppose it’s worth it.
