He really did respectfully follow the messenger's advice. He stopped, paused and chose carefully his next words and actions

@JRSRLN

That voice man... Thunderous. 

Gerard Butler was made for this role.

@kaiser5724

"This is Sparta", he politely informed the man, not wanting to hurt his feelings.

XERXES: "Why did you kill my messenger?"
LEONIDAS: "My wife said I could."

@georgegeoffrick288

"Killing a messenger sends a message "

-Leonidas

@leonardocucchiara4782

"This is Sparta." Leonidas whispered calmly

@nanamikenthoe

Truly one of the most well-delivered lines in a movie

@GlovesOffff

Gerard butler felt fearsome even when talking calmly, controlling the roller coaster of  tension in the scene, outstanding preformence

@QuasarVortex

Always stand on the edge of an infinite deep pit when you threaten someone in his own home.

@Doorbozo

This scene really inspired me. 
I've been kicking people down wells ever since this movie came out.... before I just pushed them with my hands.

@sunshineflower2286

Messenger: "threatens a king and his people in his own home and stands on the edge of a deep pit"
"Then proceeds to call him a madman"

@Apalapan97

In many occasions I've seen people refer to a frontal kick to the chest with the bottom of your foot as a "Sparta Kick". 
It's just that iconic.

@jessebarrios7534

Loved that he had a moment when he questioned his own judgment and looked to his wife for approval, and she stood by him. Powerful moment.

@ironcladnomad5639

Arguably this movie's most iconic moment, and it exists because Gerard Butler wanted just one take to try the line a bit differently.

@dukeofcyprus

The nod from his queen was the greatest act of support I've ever seen.

@matthewyates7539

1:46 This is Madness
2:08 THIS IS SPARTA!

@Archalias100

“This is Sparta”, He calmly informed the man.

@gunal2002

Messenger : Choose your next words carefully, Leonidas
Leonidas : *pulls out sword*
Messenger : That's not very careful

@emmanuelakolly6

Legend says that the dude is still falling down that pit to this day

@monsterjambrony

This line was all over the internet back in the day.
