Who plays the nerdy guy with glasses in Apollo 13?

Question

He's the one who tells everyone they need to reduce power on the shuttle if they want to get the crew home. He worked with Ken Mattingly on the reentry procedure. Am I making any sense? :) Thanks.

Answer 1

That is Matt Cain (you know him better from "Lois and Clark", as he played Superman)

Answer 2

Gary Sinise, nevermind, he played Ken Mattingly.

You can check this page and see if any of the character name looks familiar to the one you are looking for. I forget the name of the character but i think remember the one you are looking for.
