Star Wars Episode IV: A New Hope1977

[Luke is training with his lightsaber and a laser remote aboard the Millennium Falcon.]

Ben Kenobi:
Remember, a Jedi can feel the Force flowing through him.

Luke Skywalker:
You mean it controls your actions?

Kenobi:
Partially, but it also obeys your commands.

[Luke gets shot by the remote.]

Han Solo:
[laughs] Hokey religions and ancient weapons are no match for a good blaster at your side, kid.

Skywalker:
You don't believe in the Force, do you?

Solo:
Kid, I've flown from one side of this galaxy to the other. I've seen a lot of strange stuff, but I've never seen anything to make me believe there's one all-powerful Force controlling everything. There's no mystical energy field that controls my destiny. [Kenobi smiles] Anyway, it's all a lot of simple tricks and nonsense.

Kenobi:
[gets up and takes a blast helmet] I suggest you try it again, Luke. Only this time, let go your conscious self and act on instinct. [puts the helmet on Luke, which covers his eyes]

Skywalker:
But with the blast shield down, I can't even see! How am I supposed to fight?

Kenobi:
Your eyes can deceive you. Don't trust them. [remote shoots Luke] Stretch out with your feelings! [Watches Luke succeed in blocking the lasers] You see? You can do it.

Solo:
I call it luck.

Kenobi:
In my experience, there is no such thing as luck.
