Bryan Cranston in Babylon 5
Yes, he is a total badass when it comes to acting today. And, he's been in some major franchises. He will be in the new Power Rangers movie as Zordon, but he also was on the old show back in the day too. I totally forgot he had a famous part on B5. He played a White Star captain that is given the order to sacrifice his ship in order to save lives.
It is a BIG sacrifice. And, it is a powerful scene helped by Cranston's performance.
